preliminary data sheet msp 44x8g micronas 5 multistandard sound processor family release note: revision bars indicate significant changes to the previous edition. the hardware and software description in this document is valid for the msp 44x8g version a2 and following versions. 1. introduction the msp 44x8g family of multistandard sound pro- cessors covers the sound processing of all analog tv- standards worldwide, as well as the nicam digital sound standards. the full tv sound processing, start- ing with analog sound if signal-in, down to processed analog af-out, is performed on a single chip. fig. 1 ? 1 shows a simplified functional block diagram of the msp 44x8g. the high-quality a/d and d/a converters offer the full audio bandwidth of 20 khz and the backend dsp pro- cessing is performed at a 48 khz sample rate. the msp 44x8g has been designed for the usage in hybrid set-top boxes and multimedia applications. its asynchronous i 2 s slave interface allows the reception of digital stereo signals with arbitrary sample rates ranging from 5 to 50 khz. synchronization is per- formed by means of an adaptive sample rate con- verter. this generation of tv sound processing ics includes versions for processing the multichannel television sound (mts) signal conforming to the standard recom- mended by the broadcast television systems commit- tee (btsc). the dbx noise reduction, or alternatively, micronas noise reduction (mnr) is performed align- ment free. other processed standards are the japanese fm-fm multiplex standard (eia-j) and the fm stereo radio standard. the msp 44x8g versions are pin and software com- patible to other msp families. standard selection requires only a single i 2 c transmission. the msp 44x8g has built-in automatic functions: the ic is able to detect the actual sound standard automat- ically (automatic standard detection). furthermore, pilot levels and identification signals can be evaluated internally with subsequent switching between mono/ stereo/bilingual; no i 2 c interaction is necessary (auto- matic sound selection). the ics are produced in submicron cmos technology and are available in the following packages: pqfp80, plqfp64, and psdip64. fig. 1?1: simplified functional block diagram of the msp 44x8g source select scart1 scart2 scart1 scart2 scart4 scart3 mono aux aux i 2 s sound processing main sound processing dac dac adc main dac dac adc i 2 s1 i 2 s2 sound if1 sound if2 channel channel i 2 s3 de- modulator dac prescale synchron. i 2 s prescale asychron. i 2 s pre- processing scart dsp input select scart output select

preliminary data sheet msp 44x8g micronas 9 2.2. msp 44x8g sound if processing 2.2.1. analog sound if input the input pins ana_in1+, ana_in2+, and ana_in ? offer the possibility to connect two different sound if (sif) sources to the msp 44x8g. the preselected sound if signal is fed into an a/d-converter. an analog automatic gain circuit (agc) allows a wide range of input levels. the highpass filters, formed by the cou- pling capacitors at pins ana_in1+ and ana_in2+ (see section 7.3. ? application circuit ? on page 84), are sufficient in most cases to suppress video compo- nents. some combinations of saw filters and sound if mixer ics, however, show large picture components on their outputs. in this case, further filtering is recom- mended. 2.2.2. demodulator: standards and features the msp 44x8g is able to demodulate all tv-sound standards worldwide including the digital nicam sys- tem. depending on the msp 44x8g version, the fol- lowing demodulation modes can be performed: a2 systems: detection and demodulation of two sep- arate fm carriers (fm1 and fm2), demodulation and evaluation of the identification signal of carrier fm2. nicam systems: (only possible in the msp 4418g and msp 4458g). demodulation and decoding of the nicam carrier, detection and demodulation of the ana- log fm or am carrier. for d/k-nicam, the fm carrier may have a maximum deviation of 384 khz. very high deviation fm-mono: detection and robust demodulation of one fm carrier with a maximum devi- ation of 540 khz. btsc-stereo: detection and fm demodulation of the aural carrier resulting in the mts/mpx signal. detec- tion and evaluation of the pilot carrier, am demodula- tion of the (l ? r)-carrier and detection of the sap sub- carrier. processing of dbx noise reduction or micronas noise reduction (mnr). btsc-mono + sap: detection and fm demodulation of the aural carrier resulting in the mts/mpx signal. detection and evaluation of the pilot carrier, detection and fm demodulation of the sap subcarrier. process- ing of dbx noise reduction or micronas noise reduc- tion (mnr). japan stereo: detection and fm demodulation of the aural carrier resulting in the mpx signal. demodulation and evaluation of the identification signal and fm demodulation of the (l ? r)-carrier. fm-satellite sound: demodulation of one or two fm carriers. processing of high-deviation mono or narrow bandwidth mono, stereo, or bilingual satellite sound according to the astra specification. fm-stereo-radio: detection and fm demodulation of the aural carrier resulting in the mpx signal. detection and evaluation of the pilot carrier and am demodula- tion of the (l ? r)-carrier. the demodulator blocks of all msp 44x8g versions have identical user interfaces. even completely differ- ent systems like the btsc and nicam systems are controlled the same way. standards are selected by means of msp standard codes. automatic processes handle standard detection and identification without controller interaction. the key features of the msp 44x8g demodulator blocks are standard selection: the controlling of the demodula- tor is minimized: all parameters, such as tuning fre- quencies or filter bandwidth, are adjusted automati- cally by transmitting one single value to the standard select register. for all standards, spe- cific msp standard codes are defined. automatic standard detection: if the tv sound stan- dard is unknown, the msp 44x8g can automatically detect the actual standard, switch to that standard, and respond the actual msp standard code. automatic carrier mute: to prevent noise effects or fm identification problems in the absence of an fm carrier, the msp 44x8g offers a configurable carrier mute feature, which is activated automatically if the tv sound standard is selected by means of the stan- dard select register. if no fm carrier is detected at one of the two msp demodulator channels, the corre- sponding demodulator output is muted. this is indi- cated in the status register. 2.2.3. preprocessing of demodulator signals the nicam signals must be processed by a deempha- sis filter and adjusted in level. the analog demodu- lated signals must be processed by a deemphasis fil- ter, adjusted in level, and dematrixed. the correct deemphasis filters are already selected by setting the standard in the standard select register. the level adjustment has to be done by means of the fm/ am and nicam prescale registers. the necessary dematrix function depends on the selected sound standard and the actual broadcasted sound mode (mono, stereo, or bilingual). it can be manually set by the fm matrix mode register or automatically by the automatic sound selection.
msp 44x8g preliminary data sheet 10 micronas 2.2.4. automatic sound select in the automatic sound select mode, the dematrix function is automatically selected based on the identifi- cation information in the status register. no i 2 c inter- action is necessary when the broadcasted sound mode changes (e.g. from mono to stereo). the demodulator supports the identification check by switching between mono compatible standards (stan- dards that have the same fm mono carrier) automati- cally and non-audible. if b/g-fm or b/g-nicam is selected, the msp will switch between these stan- dards. the same action is performed for the standards: d/k1-fm, d/k2-fm, d/k3-fm, and d/k-nicam. switching is only done in the absence of any stereo or bilingual identification. if identification is found, the msp keeps the detected standard. in case of high bit-error rates, the msp 44x8g auto- matically falls back from digital nicam sound to ana- log fm or am mono. ta b l e 2 ? 1 summarizes all actions that take place when automatic sound select is switched on. to provide more flexibility, the automatic sound select block prepares four different source channels of demodulated sound (fig. 2 ? 2). by choosing one of the four demodulator channels, the preferred sound mode can be selected for each of the output channels (loud- speaker, headphone, etc.). this is done by means of the source select registers. the following source channels of demodulated sound are defined: ? ? fm/am ? channel: analog mono sound, stereo if available. in case of nicam, analog mono only (fm or am mono). ? ? stereo or a/b ? channel: analog or digital mono sound, stereo if available. in case of bilingual broad- cast, it contains both languages a (left) and b (right). ? ? stereo or a ? channel: analog or digital mono sound, stereo if available. in case of bilingual broad- cast, it contains language a (on left and right). ? ? stereo or b ? channel: analog or digital mono sound, stereo if available. in case of bilingual broad- cast, it contains language b (on left and right). fig. 2 ? 2 and table 2 ? 2 show the source channel assignment of the demodulated signals in case of automatic sound select mode for all sound standards. note: the analog primary input channel contains the signal of the mono fm/am carrier or the l+r signal of the mpx carrier. the secondary input channel con- tains the signal of the second fm carrier, the l ? r sig- nal of the mpx carrier, or the sap signal. fig. 2 ? 2: source channel assignment of demodulated signals in automatic sound select mode 2.2.5. manual mode fig. 2 ? 3 shows the source channel assignment of demodulated signals in case of manual mode. if man- ual mode is required, more information can be found in section 6.7. ? demodulator source channels in manual mode ? on page 81. fig. 2 ? 3: source channel assignment of demodulated signals in manual mode source select fm/am stereo or a/b stereo or a stereo or b 0 1 3 4 primary fm/am prescale nicam prescale automatic sound select channel secondary channel nicam a nicam b ls ch. matrix output-ch. matrices must be set once to stereo. sc2 ch. matrix source select fm/am (stereo or a/b) 0 1 primary fm/am prescale nicam prescale fm-matrix channel secondary channel nicam a nicam b ls ch. matrix output-ch. matrices must be set according to the standard. nicam sc2 ch. matrix

preliminary data sheet msp 44x8g micronas 13 2.5.2. main and aux outputs the main and aux output channels are adjustable in volume. a square wave beeper with adjustable fre- quency and volume can be added to them. 2.5.3. quasi-peak detector the quasi-peak readout register can be used to read out the quasi-peak level of any input source. the fea- ture is based on following filter time constants: ? attack time: 1.3 ms ? decay time: 37 ms 2.6. scart signal routing 2.6.1. scart dsp in and scart out select the scart dsp input select and scart output select blocks include full matrix switching facilities. to design a tv set with four pairs of scart-inputs and two pairs of scart-outputs, no external switching hardware is required. the switches are controlled by the acb user register (see page 31). 2.6.2. stand-by mode if the msp 44x8g is switched off by first pulling standbyq low and then (after >1 s delay) switching off dvsup and avsup, but keeping ahvsup ( ? stand-by ? -mode ), the scart switches maintain their position and function. this allows the copying from scart-input to scart-output in the tv set ? s stand-by mode. in case of power on or starting from stand-by (switch- ing on the dvsup and avsup, resetq going high 2 ms later), all internal registers except the acb regis- ter (see page 31) are reset to the default configuration (see table 3 ? 5 on page 18). the reset position of the acb register becomes active after the first i 2 c trans- mission into the baseband processing part. by trans- mitting the acb register first, the reset state can be redefined. 2.7. i 2 s bus interfaces the msp 44x8g has two kinds of interfaces: synchro- nous master/slave input/output interfaces running on 48 khz and an asynchronous slave interface. the interfaces accept a variety of formats with different sample width, bit-orientation, and wordstrobe timing. all i 2 s options are set by means of the modus or i 2 s_config register. 2.7.1. synchronous i 2 s-interface(s) the synchronous i 2 s bus interface consists of the pins: ? i2s_da_in1, i2s_da_in2/3 (i2s_da_in2 in pqfp80 package): i 2 s serial data input, 16, 18...32 bits per sample. ? i2s_da_out: i 2 s serial data output, 16, 18...32 bits per sample. ? i2s_cl: i 2 s serial clock. ? i2s_ws: i 2 s word strobe signal defines the left and right sample. if the msp 44x8g serves as the master on the i 2 s interface, the clock and word strobe lines are driven by the msp. in this mode, only 16, 32 bits per sample can be selected. in slave mode, these lines are input to the msp 44x8g and the msp clock is synchronized to 384 times the i2s_ws rate (48 khz). nicam operation is not possible in slave mode. an i 2 s timing diagram is shown in fig. 4 ? 24 on page 59. 2.7.2. asynchronous i 2 s-interface the asynchronous i 2 s slave interface allows the reception of digital stereo signals with arbitrary sample rates from 5 to 50 khz. the synchronization is per- formed by means of an adaptive sample rate con- verter. no oversampling clock is required. the following pins are used for the asynchronous i 2 s bus interface: ? i2s_ws3 (serves only as input) ? i2s_cl3 (serves only as input) ? i2s_da_in2/3 (i2s_da_in3 in pqfp80 package). the interface accepts i 2 s-input streams with msb first and with sample widths of 16,18...32 bits. with left/ right alignment and wordstrobe timing polarity, there are additional parameters available for the adaption to a variety of formats in the i 2 s-configuration regis- ter (see page 24).
msp 44x8g preliminary data sheet 14 micronas 2.8. adr bus interface for the astra digital radio system (adr), the msp 4408g, msp 4418g, and msp 4458g performs preprocessing such as carrier selection and filtering. via the 3-line adr-bus, the resulting signals are trans- ferred to the drp 3510a coprocessor, where the source decoding is performed. to be prepared for an upgrade to adr with an additional drp board, the fol- lowing lines of msp 44x8g should be provided on a feature connector: ? aud_cl_out ? i2s_da_in1, 2, or 3 ? i2s_da_out, i2s_ws, i2s_cl ? adr_cl, adr_ws, adr_da for more details, please refer to the drp 3510a data sheet. 2.9. digital control i/o pins and status change indication the static level of the digital input/output pins d_ctr_i/o_0/1 is switchable between high and low via the i 2 c-bus by means of the acb register (see page 31). this enables the controlling of external hardware switches or other devices via i 2 c-bus. the digital input/output pins can be set to high imped- ance by means of the modus register (see page 23). in this mode, the pins can be used as input. the cur- rent state can be read out of the status register (see page 25). optionally, the pin d_ctr_i/o_1 can be used as an interrupt request signal to the controller, indicating any changes in the read register status. this makes poll- ing unnecessary, i 2 c bus interactions are reduced to a minimum (see ? status register ? on page 25 and ? modus register ? on page 23). 2.10. preemphasis when using the aux output for feeding an external modulator, a preemphasis can be applied to the right channel. the signal is scaled down by ? 3 db. an overmodula- tion protection is included in the algorithm which limits the output signal to 0 dbfs. due to the nature of a pre- emphasis, its gain at high frequencies exceeds 3 db. thus, even with 0 db input signals and prescaler / vol- ume set to 0 db, clipping can occur. there are three modes present: preemphasis off, 50 s, and 75 s. (see table 3 ? 11on page 29) for the register settings. 2.11. clock pll oscillator and crystal specifications the msp 44x8g derives all internal system clocks from the 18.432 mhz oscillator. in nicam or in i 2 s- slave mode of the synchronous interface, the clock is phase-locked to the corresponding source. therefore, it is not possible to use nicam and i 2 s-slave mode of the synchronous interface at the same time. for proper performance, the msp clock oscillator requires a 18.432-mhz crystal. note that for the phase-locked modes (nicam, i 2 s-slave), crystals with tighter tolerance are required. please note also, that the asynchronous i 2 s3 slave interface uses a different locking mechanism and does not require tighter crystal tolerances.
preliminary data sheet msp 44x8g micronas 15 3. control interface 3.1. device and subaddresses the msp 44x8g is controlled via the i 2 c bus slave interface. the ic is selected by transmitting one of the msp 44x8g device addresses. in order to allow up to three msp ics to be connected to a single bus, an address select pin (adr_sel) has been implemented. with adr_sel pulled to high, low, or left open, the msp 44x8g responds to different device addresses. a device address pair is defined as a write address and a read address (see table 3 ? 1). writing is done by sending the write device address, followed by the subaddress byte, two address bytes, and two data bytes. reading is done by sending the write device address, followed by the subaddress byte and two address bytes. without sending a stop condition, reading of the addressed data is completed by sending the device read address and reading two bytes of data. refer to section 3.1.3. for the i 2 c bus protocol and to section 3.4. ? programming tips ? on page 34 for pro- posals of msp 44x8g i 2 c telegrams. see table 3 ? 2 for a list of available subaddresses. besides the possibility of hardware reset, the msp can also be reset by means of the reset bit in the con- trol register by the controller via i 2 c bus. due to the architecture of the msp 44x8g, the ic can- not react immediately to an i 2 c request. the typical response time is about 0.3 ms. if the msp cannot accept another byte of data (e.g. while servicing an internal interrupt), it holds the clock line i2c_cl low to force the transmitter into a wait state. the i 2 c bus master must read back the clock line to detect when the msp is ready to receive the next i 2 c transmission. the positions within a transmission where this may happen are indicated by ? wait ? in section section 3.1.3. the maximum wait period of the msp during normal operation mode is less than 1 ms. 3.1.1. internal hardware error handling in case of any hardware problems (e.g. interruption of the power supply of the msp), the msp ? s wait period is extended to 1.8 ms. after this time period elapses, the msp releases data and clock lines. indication and solving the error status: to indicate the error status, the remaining acknowl- edge bits of the actual i 2 c-protocol will be left high. additionally, bit[14] of control is set to one. the msp can then be reset via the i 2 c bus by transmitting the reset condition to control. indication of reset: any reset, even caused by an unstable reset line etc., is indicated in bit[15] of control. a general timing diagram of the i 2 c bus is shown in fig. 4 ? 23 on page 57. table 3 ? 1: i 2 c bus device addresses adr_sel low (connected to dvss) high (connected to dvsup) left open mode write read write read write read msp device address 80 hex 81 hex 84 hex 85 hex 88 hex 89 hex table 3 ? 2: i 2 c bus subaddresses name binary value hex value mode function control 0000 0000 00 read/write write: software reset of msp (see table 3 ? 3) read: hardware error status of msp wr_dem 0001 0000 10 write write address demodulator rd_dem 0001 0001 11 write read address demodulator wr_dsp 0001 0010 12 write write address dsp rd_dsp 0001 0011 13 write read address dsp

preliminary data sheet msp 44x8g micronas 21 3.3.2.1. standard select register the tv sound standard of the msp 44x8g demodula- tor is determined by the standard select register. there are two ways to use the standard select register: ? setting up the demodulator for a tv sound standard by sending the corresponding standard code with a single i 2 c bus transmission. ? starting the automatic standard detection for ter- restrial tv standards. this is the most comfortable way to set up the demodulator. within 0.5 s, the detection and setup of the actual tv sound standard is performed. the detected standard can be read out of the standard result register by the con- trol processor. this feature is recommended for the primary setup of a tv set. outputs should be muted during automatic standard detection. the standard codes are listed in table 3 ? 7. selecting a tv sound standard via the standard select register initializes the demodulator. this includes: agc-settings and carrier mute, tuning fre- quencies, fir-filter settings, demodulation mode (fm, am, nicam), deemphasis and identification mode. tv stereo sound standards that are unavailable for a specific msp version are processed in analog mono sound of the standard. in that case, stereo or bilingual processing will not be possible. for a complete setup of the tv sound processing from analog if input to the source selection, the transmis- sions as shown in section 3.5. on page 34 are neces- sary. there is a manual mode. 3.3.2.2. refresh of standard select register a general refresh of the standard select register is not allowed. however, the following method enables watching the msp 44x8g ? alive ? status and detection of accidental resets (only versions b6 and later): ? after power-on, bit[15] of control will be set; it must be read once to enable the reset-detection feature. ? reading of the control register and checking the reset indicator bit[15] . ? if bit[15] is ? 0 ? , any refresh of the standard select register is not allowed. ? if bit[15] is ? 1 ? , indicating a reset, a refresh of the standard select register and all other mspg registers is required. 3.3.2.3. standard result register if automatic standard detection is selected in the standard select register, status and result of the automatic standard detection process can be read out of the standard result register. the possible results are based on the mentioned standard code and are listed in table 3 ? 8. in cases where no sound standard has been detected (no standard present, too much noise, strong interfer- ers, etc.) the standard result register contains 00 00 hex . in that case, the controller has to start further actions (for example set the standard according to a preference list or by manual input). as long as the standard result register contains a value greater than 07 ff hex , the automatic standard detection is still active. during this period, the modus and standard select register must not be written. the status register will be updated when the auto- matic standard detection has finished. if a present sound standard is unavailable for a specific msp-version, it detects and switches to the analog mono sound of this standard. example: the msp 4448g will detect a b/g-nicam signal as standard 3 and will switch to the analog fm-mono sound.
