broadcast decoder SAA7133hl is a highly integrated, low cost and solid foundation for tv capture in the pc, for analog tv and digital video broadcast (dtv and dvb). the various multimedia data types are transported over the pci-bus by bus-master-write, to optimum exploit the streaming capabilities of a modern host based system (see fig.1). legacy requirements are also taken care of. the SAA7133hl meets the requirements of pc design guides 98/99 and 2001 and is pci 2.2 and advanced configuration and power interface (acpi) compliant. the analog video is sampled by 9-bit adcs, decoded by a multi-line adaptive comb filter and scaled horizontally, vertically and by field rate. multiple video output formats (yuv and rgb) are available, including packed and planar, gamma-compensated or black-stretched. analog tv sound is digitized and stereo decoded (btsc and eiaj). audio is streamed digitally via the pci-bus or the i 2 s-bus or routed as an analog signal via the loop back cable to the sound card. the SAA7133hl provides a versatile peripheral interface to support system extensions, e.g. mpeg encoding for time shift viewing. the channel decoder for digital video broadcast reception (atsc or dvb) can re-use the integrated video adcs. the transport stream (ts) or program stream (ps) is collected by a tailored interface and pumped through the pci-bus to the system memory in well-defined buffer structures. various internal events, or peripheral status information, can be enabled as an interrupt on the pci-bus. handbook, full pagewidth handbook, full pagewidth tv tuner:

semiconductors product speci?cation pci audio and video broadcast decoder SAA7133hl the SAA7133hl incorporates two 9-bit video adcs and the entire decoding circuitry of any analog tv signal: ntsc, pal and secam, including non-standard signals, such as playback from a vcr. the adaptive multi-line comb filter provides superb picture quality, component separation, sharpness and high bandwidth. the video stream can be cropped and scaled to the needs of the application. scaling down as well as zooming up is supported in the horizontal and vertical direction, and an adaptive filter algorithm prevents aliasing artifacts. with the acquisition unit of the scaler two different tasks can be defined, e.g. to capture video to the cpu for compression, and write video to the screen from the same video source but with different resolution, colour format and frame rate. the SAA7133hl contains tv sound stereo decoding from sound if (sif), for the btsc and eiaj stereo sound standards, fm and am mono sound and also non-standard signals. baseband stereo audio sampling is also implemented, e.g. for capturing from a camcorder or other external devices. the audio sampling rate can be locked to the video frame rate to ensure synchronization (lip-sync) between the video and audio data flow, e.g. for storage, compression or time shift viewing applications. the SAA7133hl incorporates analog audio pass-through and support for the analog audio loop back cable to the sound card function. the decoded video streams are fed to the pci-bus, and are also applied to a peripheral streaming interface, in itu, vip or vmi format. a possible application extension is on-board hardware mpeg compression, or other feature processing. the compressed data as ps or ts is fed back through the peripheral interface, in parallel or serial format, to be captured by the system memory through the pci-bus. the transport stream (ts) from a dtv/dvb channel decoder can be captured through the peripheral interface in the same way. audio, video and transport streams are collected in a configurable fifo with a total capacity of 1 kbyte. the dma controller monitors the fifo filling degree and master-writes the audio and video stream to the associated dma channel. the virtual memory address space (from os) is translated into physical (bus) addresses by the on-chip hardware memory management unit (mmu). the application of the SAA7133hl is supported by reference designs and a set of drivers for the windows operating system (video for windows and windows driver model compliant). 7.2 application examples the SAA7133hl enables pc tv capture applications both on the pc mother board and on pci add-on tv capture cards. figures 5 and 6 illustrate some examples of add-on card applications. figure 5 shows the basic application to capture video from analog tv sources. the proposed tuner types incorporate the rf tuning function and the if downconversion. usually the if downconversion stage also includes a single channel and analog sound fm demodulator. the philips tuners fi1286 (japan) and fi1236mk2 (usa and other ntsc countries) are suitable for m standard. the fm12x6 are special versions for additional fm radio reception. all types are suited for terrestrial broadcast and for cable reception. the tuners provide composite video cvbs and audio as second sif. these analog video and sound signals are fed to the appropriate input pins of the SAA7133hl. further analog video input signals, cvbs and/or y-c, can be connected via the board back-panel, or the separate front connectors, e.g. from a camcorder. accompanying stereo audio signals can also be fed to the SAA7133hl. video is digitized and decoded to yuv. tv sound is digitized and decoded. the SAA7133hl is able to decode stereo audio according to btsc [also including the second audio program (sap)] and stereo/dual audio according to eiaj. in addition mono decoding of fm and am sound is possible. the digital streams are pumped via dma into the pci memory space. the SAA7133hl incorporates means for legacy analog audio signal routing. the on-chip audio dacs convert the digital decoded stereo signal into analog audio. this analog audio input signal is fed via an analog audio loop back cable into the line-in of a legacy sound card. an external audio signal, that would have otherwise connected directly to the sound card, is now routed through the SAA7133hl. this analog pass-through is enabled as default by a system reset, i.e. without any driver involvement and before system set-up. during the power-up procedure, the SAA7133hl will investigate the on-board eeprom to load the board specific system vendor id and board version id into the related places of the pci configuration space. the board vendor can store other board specific data in the eeprom that is accessible via the i 2 c-bus. 2003 feb 04 17 philips semiconductors product speci?cation pci audio and

speci?cation pci audio and video broadcast decoder SAA7133hl figure 6 shows an application extension with vsb channel decoding for dtv-atsc or peripheral mpeg encoding. a combi-tuner, e.g. philips ntsc tuner fm1236, provides a dedicated dtv-if signal that can be routed directly to the channel decoder device, which converts also the decoded signal into a dtv (or bs-digital) transport stream (ts). the SAA7133hl captures this ts via the dedicated peripheral interface into the configurable internal fifo for dma into the pci memory space. the packet structure is maintained in a well-defined buffer structure in the system memory, and therefore can easily be sorted (de-multiplexed) by the cpu for proper mpeg decoding. alternatively, an external mpeg encoder chip can be inserted into the data path. this device gets the video data in itu-r bt.656 format and the audio data in i 2 s format from the SAA7133hl and gives back the mpeg encoded program stream to the SAA7133hl. handbook, full

related applications the SAA7133hl device is controlled by a low-level hardware abstraction layer (hal), contained within a device driver. this platform-independent hal initializes and controls the device and responds to interrupts forwarded by a device driver. the hal consists of objects representing the major device components (video and audio decoder, gpio pins, i 2 c-bus master) and also provides classes that can be created to represent buffers and active streams. the driver provides operating system services and forwards interrupts to the hal. a set of proxy services extends the hal interface out into user-mode. this is exposed to applications in the form of a com interface, 34com.dll. figure 8 shows these layers of software. in addition to the capture driver, this api provides the whole range of functionality to control the device. this com based class library supports interfaces for c++ as well as for visual basic and provides methods to: select one saa713x device (in case that more than one device is plugged into the pc) capture video into a fixed buffer (including clipping) capture audio (baseband stereo input or decoded tv sound) over the pci-bus into the memory (for pc-vcr application) capture video to a stream of buffers over vbi capture transport streams (mpeg data) from a channel decoder chip (ofdm, vsb, qam) for supporting digital tv applications, or from an on-board mpeg encoder chip that is fed by the video output port of the saa713x capture raw vbi sample stream to a stream of buffers over the pci-bus access to the i 2 c-bus master and gpio for controlling other peripheral circuits. handbook, full pagewidth mbl701 3xhal 34api.dll wdm tuner driver saa7130 SAA7133 saa7134 saa7135 hardware abstraction layer integrated in os device driver

documentation for streaming, i 2 c-bus and gpio access. the provided sample code will introduce the user into working with this interface. all necessary header and library files are provided. 7.4 pci interface 7.4.1 pci configuration registers the pci interface of the SAA7133hl complies with the pci specification 2.2 and supports power management and advanced configuration and power interface (acpi) as required by the pc design guide 2001 . the pci specification defines a structure of the pci configuration space that is investigated during the boot-up of the system. the configuration registers (see table 10) hold information essential for plug-and-play, to allow system enumeration and basic device set-up without depending on the device driver, and support association of the proper software driver. some of the configuration information is hard-wired in the device; some information is loaded during the system start-up. the device vendor id is hard coded to 11 31h, which is the code for philips as registered with pci-sig. the device id is hard coded to 71 33h. during power-up, initiated by pci reset, the SAA7133hl fetches additional system information via the i 2 c-bus from the on-board eeprom, to load actual board type specific codes for the system vendor id, sub-system id (board version) and acpi related parameters into the configuration registers. handbook, halfpage

semiconductors product speci?cation pci audio and video broadcast decoder SAA7133hl 7.4.2 acpi and power states the pci specification 2.2 requires support of advanced configuration and power interface specification 1.0 (acpi); more details are defined in the pci power management specification 1.0 . the power management capabilities and power states are reported in the extended configuration space. the main purpose of acpi and pci power management is to tailor the power consumption of the device to the actual needs. the SAA7133hl supports all four acpi device power states (see table 11). the pin prop_rst of the peripheral interface is switched active low during the pci reset procedure, and for the duration of the d3-hot state. peripheral devices on board of the add-on card should use the level of this signal prop_rst to switch themselves in any power-save mode (e.g. disable device) and reset to default settings on the rising edge of signal prop_rst. the length of signal prop_rst is programmable. 7.4.3 dma and configurable fifo the SAA7133hl supports seven dma channels to master-write captured active video, audio, raw vbi and dtv/dvb transport streams (ts) and mpeg streams (ps and ts) into the pci memory. each dma channel contains inherently the definition of two buffers in the system address space, e.g. for odd and even fields in case of interlaced video, or two alternating buffers to capture continuous audio stream. the dma channels share in time and space one common fifo pool of 256 dwords (1024 bytes) total. it is freely configurable how much fifo capacity is associated with which dma channel. furthermore, a preferred minimum burst length can be programmed, i.e. the amount of data to be collected before the request for the pci-bus is issued. this means that latency behaviour per dma channel can be tailored and optimized for a given application. in the event that the fifo of a certain channel overflows due to latency conflict on the bus, graceful overflow recovery is applied. the mount of data that gets lost because it could not be transmitted, is monitored (counted) and the pci-bus address pointer is incremented accordingly. thus new data will be written to the correct memory place, after the latency conflict is resolved. table 11 power management table table 12 fifo con?guration: typical example power state description d0 normal operation: all functions accessible and programmable. the default setting after reset and before driver interaction (d0 un-initialized) switches most of the circuitry of the SAA7133hl into the power-down mode, effectively such as d3-hot. d1 first step of reduced power consumption: no functional operation; program registers are not accessible, but content is maintained. most of the circuitry of the SAA7133hl is disabled with exception of the crystal and real-time clock oscillators, so that a quick recovery from d1 to d0 is possible. d2 second step of reduced power consumption: no functional operation; program registers are not accessible, but content is maintained. all functional circuitry of the SAA7133hl is disabled, including the crystal and clock oscillators. d3-hot lowest power consumption: no functional operation. the content of the programming registers gets lost and is set to default values when returning to d0. dma data stream data rate fifo size programmable to

physical addressing most operating systems allocate memory to requesting applications for dma as continuous ranges in virtual address space. the data flow over the pci-bus points to physical addresses, usually not continuous and split in pages of 4 kbytes (intel architecture, most unix systems, power pc). the association between the virtual (logic) address space and the fragmented physical address space is defined in page tables (system files); see fig.10. the SAA7133hl incorporates hardware support (mmu) to translate virtual to physical addresses on the fly, by investigating the related page table information. this hardware support reduces the demand for real-time software interaction and interrupt requests, and therefore saves system resources. handbook, full pagewidth

7.4.5 s tatus and interrupts on pci- bus the SAA7133hl provides a set of status information about internal signal processing, video and audio standard detection, peripheral inputs and outputs (pins gpio) and behaviour on the pci-bus. this status information can be conditionally enabled to raise an interrupt on the pci-bus, e.g. completion of a certain dma channel or buffer, or change in a detected tv standard, or the state of peripheral devices. the cause of an issued interrupt is reported in a dedicated register, even if the original condition has changed before the system was able to investigate the interrupt. 7.5 analog tv standards analog tv signals are described in three categories of standards: basic tv systems: defining frame rate, number of lines per field, levels of synchronization signals, blanking, black and white, signal bandwidth and the rf modulation scheme colour transmission: defining colour coding and modulation method sound and stereo: defining coding for transmission. tv signals that are broadcasted usually conform fairly accurately to the standards. transmission over the air or through a cable can distort the signal with noise, echoes, crosstalk or other disturbances. video signals from local consumer equipment, e.g. vcr, camcorder, camera, game console, or even dvd player, often do not follow the standard specification very accurately. playback from video tape cannot be expected to maintain correct timing, especially not during feature mode (fast forward, etc.). tables 14, 15 and 16 list some characteristics of the various tv standards. the SAA7133hl decodes all colour tv standards and non-standard signals as generated by video tape recorders e.g. automatic video standard detection can be applied, with preference options for certain standards, or the decoder can be forced to a dedicated standard. the SAA7133hl incorporates btsc and eiaj stereo decoding and tv mono sound decoding on chip. baseband stereo audio can be fed into the device as analog signal. table 14 overview of basic tv standards main parameters standard unit m n b g, h i d/k l rf channel width 6 6 7 7 8 7 8 mhz video bandwidth 4.2 4.2 5 5 5.5 6 6

five analog video input pins: composite video signals (cvbs), from tuner or external source s-video signals (pairs of y-c), e.g. from camcorder dtv/dvb low-if signal, from an appropriate dtv or combi-tuner. analog anti-alias filters are integrated on chip and therefore, no external filters are required. the device also contains automatic clamp and gain control for the video input signals, to ensure optimum utilization of the adc conversion range. the nominal video signal amplitude is 1 v (p-p) and the gain control can adapt deviating signal levels in the range of +3 db to - 6 db. the video inputs are digitized by two adcs of 9-bit resolution, with a sampling rate of nominal 27 mhz (the line-locked clock) for analog video signals. 7.6.2 v ideo synchronization and line - locked clock the SAA7133hl recovers horizontal and vertical synchronization signals from the selected video input signal, even under extremely adverse conditions and signal distortions. such distortions are noise, static or dynamic echoes from broadcast over air, crosstalk from neighbouring channels or power lines (hum), cable reflections, time base errors from video tape play-back and non-standard signal levels from consumer type video equipment (e.g. cameras, dvd). the heart of this tv synchronization system is the generation of the line-locked clock (llc) of nominal 27 mhz, as defined by itu-r bt.601. the llc ensures orthogonal sampling, and always provides a regular pattern of synchronization signals, that is a fixed and well defined number of clock pulses per line. this is important for further video processing devices connected to the peripheral video port (pins gpio). it is very effective to run under the llc of 27 mhz, especially for on-board hardware mpeg encoding devices, since mpeg is defined on this clock and sampling frequency. 7.6.3 v ideo decoding and automatic standard detection the SAA7133hl incorporates colour decoding for any analog tv signal. all colour tv standards and flavours of ntsc, pal, secam and non-standard signals (vcr) are automatically recognized and decoded into luminance and chrominance components, i.e. y-c b -c r , also known as yuv. the video decoder of the SAA7133hl incorporates an automatic standard detection, that does not only distinguish between 50 and 60 hz systems, but also determines the colour standard of the video input signal. various preferences (look first) for automatic standard detection can be chosen, or a selected standard can be forced directly. 7.6.4 a daptive comb filter the SAA7133hl applies adaptive comb filter techniques to improve the separation of luminance and chrominance components in comparison to the separation by a chroma notch filter, as used in traditional tv colour decoder technology. the comb filter compares the signals of neighbouring lines, taking into account the phase shift of the chroma subcarrier from line to line. for ntsc the signals of three adjacent lines are investigated, and in the event of pal the comb filter taps are spread over four lines. comb filtering achieves higher luminance bandwidth, resulting in sharper picture and detailed resolution. comb filtering further minimizes colour crosstalk artifacts, which would otherwise produce erroneous colours on detailed luminance structures. the comb filter as implemented in the SAA7133hl is adaptive in two ways: adaptive to transitions in the picture content adaptive to non-standard signals (e.g. vcr). the integrated digital delay lines are always exactly correct, due to the applied unique line-locked sampling scheme (llc). therefore the comb filter does not need to be switched off for non-standard signals and remains operating continuously. 7.6.5 m acrovision detection the SAA7133hl detects if the decoded video signal is copy protected by the macrovision system. the detection logic distinguishes the three levels of the copy protection as defined in rev. 7.01, and are reported as status information. the macrovision detection works also for copy protected video signals, which contain inverted bursts but no agc pulses and no pseudo syncs. those signals come from some so-called macrovision-killer boxes. the decoded video stream is not effected directly, but application software and operation system (os) has to ensure, that this video stream maintains tagged as copy protected, and such video signal would leave the system only with the reinforced copy protection. the multi-level macrovision detection on the video capture side supports 2003 feb 04 27 philips semiconductors product speci?cation pci audio and video broadcast decoder SAA7133hl proper tv re-encoding on the output point, e.g. by philips tv encoders saa712x or saa7102. 7.6.6 v ideo scaling the SAA7133hl incorporates a filter and processing unit to downscale or upscale the video picture in the horizontal and vertical dimension, and in frame rate (see figs 11 and 12). the phase accuracy of the re-sampling process is 1 64 of the original sample distance. this is equivalent to a clock jitter of less than 1 ns. the filter depth of the anti-alias filter adapts to the scaling ratio, from 10 taps horizontally for scaling ratios close to 1 : 1, to up to 74 taps for an icon sized video picture. most video capture applications will typically require for downscaling. but some zooming is required for conversion of itu sampling to square pixel (sqp), or to convert the 240 lines of an ntsc field to 288 lines to comply with ccitt video phone formats. the scaling acquisition definition also includes cropping, frame rate reduction, and defines the amount of pixels and lines to be transported through dma over the pci-bus. two programming pages are available to enable re-programming of the scaler in the shadow of the running processing, without holding or disturbing the flow of the video stream. alternatively, the two programming pages can be applied to support two video destinations or applications with different scaler settings, e.g. firstly to capture video to cpu for compression (storage, video phone), and secondly to preview the picture on the monitor screen. a separate scaling region is dedicated to capture raw vbi samples, with a specific sampling rate, and be written into its own dma channel. handbook, full pagewidth mhb997 active video area video region

inserted in camcorders e.g. use for video editing copy guard management system (cgms) codes, to indicate copy protected video material, sometimes combined with format information [wide screen signalling (wss)]. this information is coded in the unused lines of the vertical blanking interval, between the vertical sync pulse and the active visible video picture. so-called full-field data transmission is also possible, utilizing all video lines for data coding. the SAA7133hl supports capture of vbi data by the definition of a vbi region to be captured as raw vbi samples, that will be sliced and decoded by software on the host cpu. the raw sample stream is taken directly from the adc and is not processed or filtered by the video decoder. the sampling rate of raw vbi can be adjusted to the needs of the data slicing software. 7.6.8 s ignal levels and colour space analog tv video signals are decoded into its components luminance and colour difference signals (yuv) or in its digital form y-c b -c r . itu-r bt.601 defines 720 pixels along the line (corresponding to a sampling rate of 27 mhz divided by two), and a certain relationship from level to number range (see fig.13). the video components do not use the entire number range, but leave some margin for overshoots and intermediate values during processing. for the raw vbi samples there is no official specification how to code, but it is common practice to reserve the lower quarter of the number range for the sync, and to leave some room for overmodulation beyond the nominal white amplitude (see fig.14). the automatic clamp and gain control at the video input, together with the automatic chroma gain control of the SAA7133hl, ensures that the video components stream at the output comply to the standard levels. beyond that additional brightness, contrast, saturation and hue control can be applied to satisfy special needs of a given application. the raw vbi samples can be adjusted independent of the active video. the SAA7133hl incorporates the yuv-to-rgb matrix (optional), the rgb-to-yuv matrix and a three channel look-up table in between (see fig.15). under nominal settings, the rgb space will use the same number range as defined by the itu and shown in fig.13a for luminance, between 16 and 235. as graphic related applications are based on full-scale rgb, i.e. 0 to 255, the range can be stretched by applying appropriate brightness, contrast and saturation values. the look-up table supports gamma correction (freely definable), and allows other non-linear signal transformation such as black stretching. the analog tv signal applies a quite strong gamma pre-compensation (2.2 for ntsc and 2.8 for pal). as computer monitors exhibit a gamma (around 2.5), the difference between gamma pre-compensation and actual screen gamma has to be corrected, to achieve best contrast and colour impression. the SAA7133hl offers a multitude of formats to write video streams over the pci-bus: yuv and rgb colour space, 15-bit, 16-bit, 24-bit and 32-bit representation, packed and planar formats. for legacy requirements (vfw) a clipping procedure is implemented, that allows the definition of 8 overlay rectangles. this process can alternatively be used to associate alpha values to the video pixels. 2003 feb 04 30 philips semiconductors product speci?cation pci audio and video broadcast

available locally through the video side port (vp), using some of the gpio pins. two types of applications are intended: streaming real-time video to a video side port at the vga card, e.g. via ribbon cable over the top feeding video stream to a local mpeg compression device on the same pci board, e.g. for a time shift viewing application. the video port of the SAA7133hl supports the following 8 and 16-bit wide yuv video signalling standards (see table 6): vmi: 8-bit wide data stream, clocked by llc = 27 mhz, with discrete sync signals hsync, vsync and vactive itu-r bt.656, parallel: 8-bit wide data stream, clocked by llc = 27 mhz, synchronization coded in sav and eav codes vip 1.1 and 2.0: 8-bit or 16-bit wide data stream, clocked by llc = 27 mhz, synchronization coded in sav and eav codes (with vip extensions) zoom video (zv): 16-bit wide pixel stream, clocked by llc/2 = 13.5 mhz, with discrete sync signals hsync and vsync itu-r bt.601 direct (dmsd): 16-bit wide pixel stream, clocked by llc = 27 mhz, with discrete sync signals hsync, vsync/fid and cref raw dtv/dvb sample stream: 9-bit wide data, clocked with a copy of signal x_clk_in. the vip standard is designed to transport scaled video and discontinuous data stream by allowing the insertion of 00 as marker for empty clock cycles. for the other video port standards, a data valid flag or gated clock can be applied. 7.7 tv sound 7.7.1 tv sound stereo decoding the SAA7133 hl incorporates tv sound decoding from the sound intermediate frequency (sif) signal. the analog sif signal is taken from the tuner, digitized and digitally fm or am demodulated. if one of the supported tv sound standards is found (btsc, eiaj, mono), the pilot tone is investigated (mono, stereo, dual) and the signal is properly stereo or dual decoded. the SAA7133hl supports the stereo audio standards btsc (+sap) and eiaj and all mono standards on-chip. dbx-tv noise reduction and de-emphasis filters are also integrated. the digital fm demodulation maintains stable phase accuracy, resulting into improved channel separation, compared to traditional analog demodulation. tv sound decoding operates at a 32 khz sample rate, resulting in an audio bandwidth of up to 15 khz. the SAA7133hl incorporates baseband stereo audio adcs, to capture sound signals associated with external video sources, e.g. camera, camcorder or vcr. 2003 feb 04 32 philips semiconductors product speci?cation pci audio and video broadcast decoder SAA7133hl for concurrent capture of audio and video signals, it is important to maintain synchronization between the two streams. the spoken word and other sound should match the displayed picture within a video frame ( 1 / 30 s respectively 1 / 25 s lip-sync). the SAA7133hl has special means to lock the audio sampling clock to the video frame frequency (flc), so that a programmable but constant number of audio samples is associated with each video frame. this is especially important for video editing, compression and recording, e.g. time shift viewing. there is no drift between the audio and video streams, not even for longer recording times. table 17 tv sound decoding, supported feature processing and sampling rate notes 1. simultaneous decoding of stereo and sap. dbx-tv noise reduction either on stereo or on sap. 2. default pass-through of l1 and r1. 7.7.2 a dditional audio

commercials) incredible mono (this algorithm adds stereo-like sound impression to monaural audio signals) incredible stereo (this algorithm makes stereo sound impression wider. the distance between

udio interfaces the sif input can handle the sound subcarrier signal from the tuner. baseband audio signals can be captured through the stereo line-in inputs left1, right1, left2 and right2 or the i 2 s-bus input. the decoded and possibly enhanced digital audio stream can be captured through dedicated dma into the pci memory space, or to the output in i 2 s-bus format, e.g. to a peripheral digital sound amplifier. the third way is to re-convert the audio signal to analog via the integrated audio stereo dacs and feed it directly through the loop back cable to the sound card or to headphones for local monitoring. a master clock output (a_clk_master) for synchronous clocking of external devices is available via a gpio output. the audio block is also able to work synchronously to an external audio reference clock (a_ref_clk). 7.7.4 d efault analog audio pass - through and loop back cable most operating systems are prepared to deal with audio input at only one single entry point, namely at the sound card function. therefore the sound associated with video has to get routed through the sound card. the SAA7133hl supports analog audio pass-through and the loop back cable on-chip. no external components are required. the audio signal, that was otherwise connected to the sound card line-in, e.g. analog sound from a cd-rom drive, has to be connected to one of the inputs of the SAA7133hl. by default, after a system reset and without involvement of any driver, this audio signal is passed through to the analog audio output pins, that will feed the loop back cable to the sound card line-in connector. the av capture driver has to open the default pass-through and switch in the tv sound signal by will. 7.8 dtv/dvb channel decoding and mpeg ts or ps capture the SAA7133hl also supports application extension to cover the reception of digital tv broadcast [dtv/atsc, dvb (t/c/s) or bs-digital]. the low if signal from a hybrid tuner is fed to a peripheral channel decoder, to decode it into the transport stream. this ts, accompanied by a clock and handshake signals [start of packet (sop), etc.] can be captured by the SAA7133hl, in serial or parallel format. the ts packets are written in a structured way in dedicated dma definition into the pci memory space. toggling between two dma buffers is supported automatically. the SAA7133hl supports also capturing of mpeg elementary and program streams. this expands the connectivity to mpeg encoders like the philips saa6752hs or similar devices. 7.9 control of peripheral devices 7.9.1 i 2 c- bus master the SAA7133hl incorporates an i 2 c-bus master to set-up and control peripheral devices such as tuner, dtv/dvb channel decoder, audio dsp co-processors, etc. the i 2 c-bus interface itself is controlled from the pci-bus on a command level, reading and writing byte by byte. the actual i 2 c-bus status is reported (status register) and, as an option, can raise error interrupts on the pci-bus. at pci reset time, the i 2 c-bus master receives board specific information from the on-board eeprom to update the pci configuration registers. the i 2 c-bus interface is multi-master capable and can assume slave operation too. this allows application of the device in the stand-alone mode, i.e. with the pci-bus not connected. under the slave mode, all internal programming registers can be reached via the i 2 c-bus with exception of the pci configuration space. 7.9.2 p ropagate reset the pci system reset and acpi power management state d3 is propagated to peripheral devices by the dedicated pin prop_rst. this signal is switched to active low by reset and d3, and is only switched high under control of the device driver by will. the intention is that peripheral devices will use signal prop_rst as chip-enable (ce). the peripheral devices should enter a low power consumption state if pin prop_rst = low, and reset into default setting at the rising edge. 7.9.3 gpio the SAA7133hl offers a set of general purpose input/output (gpio) pins, to interface to on-board peripheral circuits; see also table 6. these gpios are intended to take over dedicated functions: digital video port output: 8-bit or 16-bit wide (including raw dtv) digital audio serial output: i.e. i 2 s-bus output transport stream input: C parallel (also applicable for program stream and elementary stream) C serial (also applicable as i 2 s-bus input) 2003 feb 04 34 philips semiconductors product speci?cation pci audio and video broadcast decoder SAA7133hl peripheral interrupt input: four gpio pins of the SAA7133hl can be enabled to raise an interrupt on the pci-bus. by this means, peripheral devices can directly intercept with the device driver on changed status or error conditions. any gpio pin that is not used for a dedicated function is available for direct read and write access via the pci-bus. any gpio pin can be selected individually as input or output (masked write). by these means, very tailored interfacing to peripheral devices can be created via the SAA7133hl capture driver running on windows operating systems. at system reset (pci reset) all gpio pins will be set to 3-state and input, and the logic level present on the gpio pins at that moment will be saved into a special strap register. all gpio pins have an internal pull-down resistor (low level), but can be strapped externally with a 4.7 k w resistor to the supply voltage (high level). the device driver can investigate the strap register for information about the hardware configuration of a given board. 8 boundary scan test the SAA7133hl has built-in logic and five dedicated pins to support boundary scan testing which allows board testing without special hardware (nails). the SAA7133hl follows the ieee std. 1149.1 - standard test access port and boundary - scan architecture set by the joint test action group (jtag) chaired by philips. the 5 special pins are: test mode select (tms), test clock (tck), test reset ( trst), test data input (tdi) and test data output (tdo). the boundary scan test (bst) functions bypass, extest, sample, clamp and idcode are all supported (see table 18). details about the jtag bst-test can be found in the specification ieee std. 1149.1 . a file containing the detailed boundary scan description language (bsdl) description of the SAA7133hl is available on request. 8.1 initialization of boundary scan circuit the test access port (tap) controller of an ic should be in the reset state (test_logic_reset) when the ic is in the functional mode. this reset state also forces the instruction register into a functional instruction such as idcode or bypass. to solve the power-up reset, the standard specifies that the tap controller will be forced asynchronously to the test_logic_reset state if pin trst is at low level. 8.2 device identi?cation codes when the idcode instruction is loaded into the bst instruction register, the identification register will be connected internally between pins tdi and tdo of the ic. the identification register will load a component specific code during the capture_data_register state of the tap controller and this code can subsequently be shifted out. at board level, this code can be used to verify component manufacturer, type and version number. the device identification register contains 32 bits, numbered 31 to 0, where bit 31 is the most significant bit (nearest to tdi) and bit 0 is the least significant bit (nearest to tdo) (see fig.16). a device identification register is specified in ieee std. 1149.1b-1994 . it is a 32-bit register which contains fields for the specification of the ic manufacturer, the ic part number and the ic version number. its biggest advantage is the possibility to check for the correct ics mounted after production and determination of the version number of ics during field service. table 18 bst instructions supported by the SAA7133hl instruction description bypass this mandatory instruction provides a minimum length serial path (1 bit) between pins tdi and tdo when no test operation of the component is required. extest this mandatory instruction allows testing of off-chip circuitry and board level interconnections. sample this mandatory instruction can be used to take a sample of the inputs during normal operation of the component. it can also be used to preload data values into the latched outputs of the boundary scan register. clamp this optional instruction is useful for testing when not all ics have bst. this instruction addresses the bypass register while the boundary scan register is in external test mode. idcode this optional instruction will provide information on the components manufacturer, part number and version number. 2003 feb 04 35 philips semiconductors

pci audio and video broadcast decoder SAA7133hl notes 1. input leakage currents include high-impedance output leakage for all bidirectional buffers with 3-state outputs. 2. pins without pull-up resistors must have a 3 ma output current. pins requiring pull-up resistors must have 6 ma; these are pins frame#, trdy#, irdy#, devsel#, serr#, perr#, int_a and stop#. 3. this parameter is to be interpreted as the cumulative edge rate across the specified range, rather than the instantaneous rate at any point within the transition range. 4. req# and gnt# are point-to-point signals and have

mount packages this text gives a very brief insight to a complex technology. a more in-depth account of soldering ics can be found in our data handbook ic26; integrated circuit packages (document order number 9398 652 90011). there is no soldering method that is ideal for all surface mount ic packages. wave soldering can still be used for certain surface mount ics, but it is not suitable for fine pitch smds. in these situations reflow soldering is recommended. 13.2 re?ow soldering reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. several methods exist for reflowing; for example, convection or convection/infrared heating in a conveyor type oven. throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. typical reflow peak temperatures range from 215 to 250 c. the top-surface temperature of the packages should preferable be kept below 220 c for thick/large packages, and below 235 c for small/thin packages. 13.3 wave soldering conventional single wave soldering is not recommended for surface mount devices (smds) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. to overcome these problems the double-wave soldering method was specifically developed. if wave soldering is used the following conditions must be observed for optimal results: use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. for packages with leads on two sides and a pitch (e): C larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; C smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves at the downstream end. for packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves downstream and at the side corners. during placement and before soldering, the package must be fixed with a droplet of adhesive. the adhesive can be applied by screen printing, pin transfer or syringe dispensing. the package can be soldered after the adhesive is cured. typical dwell time is 4 seconds at 250 c. a mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 13.4 manual soldering fix the component by first soldering two diagonally-opposite end leads. use a low voltage (24 v or less) soldering iron applied to the flat part of the lead. contact time must be limited to 10 seconds at up to 300 c. when using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 c. 2003 feb 04 49 philips semiconductors product speci?cation pci audio and video broadcast decoder SAA7133hl 13.5 suitability of surface mount ic packages for wave and re?ow soldering methods notes 1. for more detailed information on the bga packages refer to the (lf)bga application note (an01026); order a copy from your philips semiconductors sales office. 2. all surface mount (smd) packages are moisture sensitive. depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). for details, refer to the drypack information in the data handbook ic26; integrated circuit packages; section: packing methods . 3. these packages are not suitable for wave soldering. on versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit board and the heatsink. on versions with the heatsink on the top side, the solder might be deposited on the heatsink surface. 4. if wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. the package footprint must incorporate solder thieves downstream and at the side corners. 5. wave soldering is suitable for lqfp, tqfp and qfp packages with a pitch (e) larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 6. wave soldering is suitable for ssop, tssop, vso and vssop packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5
