Notes) 1. The MOS structure of this IC has a low tolerance for static electricity, so full care should be given for measures to prevent electrostatic discharge. 2. For noise and latch-up countermeasures, be sure to connect a by-pass capacitor (0.1F or more) between each power supply pin (VH, VL) and GND. 3. To protect the CCD image sensor, clamp the SUB pin output at VH before input to the CCD image sensor. -8-

CXD3406GA
Timing Generator Block Serial Interface Control The CXD3406GA's timing generator block basically loads and reflects the timing generator block serial interface data sent in the following format in the readout portion at the falling edge of HD. Here, readout portion specifies the horizontal period during which V1A/B and V3A/B, etc. take the ternary value. Note that some items reflect the timing generator block serial interface data at the falling edge of VD or the rising edge of SEN1.

Control data: [AF drive] The CXD3406GA controls the drive of the vertical cut-out area of the line in AF1/AF2 mode by using control data D16 to D23 CDAT. This mode has a function on purpose to raise frame rate for auto focus (AF), and cannot support operation such as electrical image stabilization. The AF drive bits are loaded to the CXD3406GA and reflected at the falling edge of VD. As shown in the figure below, first, the fixed stage is swept at high speed, and it goes to readout period and vertical OB period. Then normal transfer is performed equivalent to draft mode from the frame shift to the stage specified by the serial interface data to the timing of the falling edge of the next VD. Therefore, the number of frame shift stages applied to CDAT and the control by VD period are conditions for its application.
VD High-speed sweep V1A Vck MODE CDAT 0 00h 4 FFh 0 00h Normal transfer
Frame shift
The number of high-speed sweep are different according to the selected mode. They are specified as follows. AF1 mode: 138 stages (0 to 7H) AF2 mode: 208 stages (0 to 11H) The frame shift data is expressed as shown in the table below using D16 to D23 CDAT. MSB D23 0 D22 1 6 D21 1 D20 0 D19 1 D18 0 9 D17 0 LSB D16 1 CDAT is expressed as 69h .
Its definition area is specified as follows. AF1 mode: 00h CDAT FFh (11 to 23H) AF2 mode: 00h CDAT FFh (14 to 27H)

CXD3406GA
Control data/shutter data: [Electronic shutter] The CXD3406GA realizes various electronic shutter functions by using control data D13 to D14 SMD and shutter data D10 to D19 SVD, D20 to D31 SHD and D32 to D41 SPL. These functions are described in detail below. First, the various modes are shown below. These modes are switched using control data D13 to D14 SMD. D14 0 0 1 1 D13 0 1 0 1 Description of operation Electronic shutter stopped mode High-speed/low-speed shutter mode HTSG control mode
The electronic shutter data is expressed as shown in the table below using D20 to D31 SHD as an example. However, MSB (D31) is a reserve bit for the future specification, and it is handled as a dummy on this IC. MSB D31 X D30 0 1 D29 0 D28 1 D27 1 D26 1 C D25 0 D24 0 D23 0 D22 0 3 D21 1 LSB D20 1 SHD is expressed as 1C3h .
[Electronic shutter stopped mode] During this mode, all shutter data items are invalid. SUB is not output in this mode, so the shutter speed is the accumulation time for one field.
[High-speed/low-speed shutter mode] During this mode, the shutter data items have the following meanings. Symbol SVD SHD SPL Data D10 to D19 D20 to D31 D32 to D41 Description Number of vertical periods specification (000h SVD 3FFh) Number of horizontal periods specification (000h SHD 7FFh) Vertical period specification for high-speed shutter operation (000h SPL 3FFh)
The period during which SVD and SHD are specified together is the shutter speed. Concretely, when specifying high-speed shutter, SVD is set to "000h". (See the figure.) During low-speed shutter, or in other words when SVD is set to "001h" or higher, the serial interface data is not loaded until this period is finished. The vertical period indicated here corresponds to one field in each drive mode. In addition, the number of horizontal periods applied to SHD can be considered as (number of SUB pulses - 1). However, in the frame mode A field, it matches (number of SUB pulses + 1). This is a specification for flickerless when the same mode is repeated. But this change may not occur because of flickerless depending on the conditions during low-speed shutter. Note) The bit data definition area is assured in terms of the CXD3406GA functions, and does not assure the CCD characteristics. - 25 -

Further, SPL can be used during this mode to specify the SUB output at the desired vertical period during the low-speed shutter period. In the case below, SUB is output based on SHD at the SPL vertical period out of (SVD + 1) vertical periods.
SPL VD SHD V1A SUB WEN SMD SPL SVD SHD 10 001h 002h 10Fh 01 000h 000h 0A3h SVD
Incidentally, SPL is counted as "000h", "001h", "002h" and so on in conformance with SVD. Using this function, it is possible to achieve smooth exposure time transitions when changing from low-speed shutter to high-speed shutter or vice-versa.

[HTSG control mode] During this mode, all shutter data items are invalid. The V1A/B and V3A/B ternary level outputs are stopped, so the shutter speed is the value obtained by adding the shutter speed specified in the preceding vertical period to the vertical period during which these readout pulses are stopped as shown in the figure.

This chart is a driving timing chart example of electronic shutter normal operation. Data exposed at D includes blooming component. For details, see the CCD image sensor Data Sheet. The CXD3406GA does not generate the pulse to control mechanical shutter operation. The switching timing of the drive mode and the electronic shutter data is not the same.

CCD Signal Processor Block Serial Interface Control The CXD3406GA's CCD signal processor block basically loads the CCD signal processor block serial interface data sent in the following format at the rising edge of SEN2, and the setting values are then reflected to the operation 6 ADCLKI clocks after that. CCD signal processor block serial interface control requires clock input to ADCLKI in order to load and reflect the serial interface data to operation, so this should normally be performed when the timing generator block is in the normal operation mode.

There are four categories of CCD signal processor block serial interface data: standby control data, PGA gain setting data, OB clamp level setting data, and input pulse polarity setting data. Note that when data from multiple categories is loaded consecutively, the data for the category loaded last is valid and data from other categories is lost. When transferring data from multiple categories, raise SEN2 for each category and wait until the setting value 6 ADCKLI clocks after that has been reflected to operation, then transmit the next category. The detail of each data are described below. Standby Control Data Data D00 D01 to D03 D04 to D14 D15 Symbol TEST CTG Test code Category switching Function Data = 0 Set to 0. D01 to D03 CTG Data = 1

Notes on Operation 1. Be sure to start up the timing generator block VL and VH pin power supplies at the timing shown in the figure below in order to prevent the SUB pin of the CCD image sensor from going to negative potential. In addition, start up the timing generator block VDD1, VDD2, VDD3, VDD4 and VDD5 pin and CCD signal processor block DVDD1, DVDD2, AVDD1, AVDD2, AVDD3, AVDD4 and AVDD5 pin power supplies at the same time either before or at the same time as the VH pin power supply is started up.

2. Reset the timing generator block and CCD signal processor block during power-on. The timing generator block is reset by inputting the reset signal to the RST pin. The CCD signal processor block is reset by initializing the serial data. 3. Separate the timing generator block VDD1, VDD2, VDD3, VDD4 and VDD5 pins from the CCD signal processor block DVDD1, DVDD2, AVDD1, AVDD2, AVDD3, AVDD4 and AVDD5 pins. Also, the ADC output driver stage is connected to the dedicated power supply pin DVDD1. Separating this pin from other power supplies is recommended to avoid affecting the internal analog circuits. 4. The difference in potential between the timing generator block VDD4 pin supply voltage 3 VDDc and the CCD signal processor block DVDD1, DVDD2, AVDD1, AVDD2, AVDD3, AVDD4 and AVDD5 pin supply voltages 1 VDDe, 2 VDDf and 3 VDDg should be 0.1V or less. 5. The timing generator block and CCD signal processor block ground pins should use a shared ground which is connected outside the IC. When the set ground is divided into digital and analog blocks, connect the timing generator block ground pins to the digital ground and the CCD signal processor block ground pins to the analog ground. The difference in potential between the timing generator block VSS1, VSS2, VSS3, VSS4, VSS5, VSS6 and VM and the CCD signal processor block DVSS1, DVSS2, DVSS3, AVSS1, AVSS2, AVSS3, AVSS4, AVSS5 and AVSS6 should be 0.1V or less. 6. Do not perform serial communication with the CCD signal processor block during the effective image period, as this may cause the picture quality to deteriorate. In addition, using SCK2, SSI2 and SEN2, which are used by the CCD signal processor block, use of the dedicated ports is recommended. When using these pins as shared ports with the timing generator block or other ICs, be sure to thoroughly confirm the effects on picture quality before use. - 45 -
