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-

CXD3423GA
Timing Generator Block Serial Interface Control The CXD3423GA'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 V3A/B and V5A/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.

CXD3423GA
Detailed Description of Each Data Shared data: D08 CTG [Category] Of the data provided to the CXD3423GA by the timing generator block serial interface, the CXD3423GA loads D10 and subsequent data to each data register as shown in the table below according to D08 . D08 0 1 Description of operation Loading to control data register Loading to shutter data register
Note that the CXD3423GA can apply these categories consecutively within the same vertical period. However, care should be taken as the data is overwritten if the same category is applied.
Control data: D12 , D13 MODE [Drive mode] The CXD3423GA drive mode can be switched as follows. However, the drive mode bits are loaded to the CXD3423GA and reflected at the falling edge of VD. D13 0 0 1 1 D12 0 1 0 1 Description of operation Draft mode (default) Frame mode AF mode1 Test mode
1 The test mode results in ICX284/434 mode. Draft mode is the pulse elimination drive mode. This is a high frame rate drive mode that can be used for purposes such as monitoring and moving pictures. AF mode is the drive mode for applications with an even higher frame rate, and is used for auto focus (AF). Frame mode is the drive mode in which the data for all lines of the ICX284/432/434 are read.
Control data: D16 NTPL [SSG function switching] The CXD3423GA internal SSG output pattern can be switched as follows. However, the drive mode bits are loaded to the CXD3423GA and reflected at the falling edge of VD. The default is "NTSC". D16 0 1 Description of operation NTSC equivalent pattern output (internal SSG) PAL equivalent pattern output (internal SSG)

Control data: D17 CCD [Used CCD switching] This specifies the CCD image sensor to be used. However, like the drive mode bits, the CCD switching bits are loaded to the CXD3423GA and reflected at the falling edge of VD. The default is "ICX432". D17 0 1 Description of operation ICX432 ICX284/434
Control data: D32 FGOB [Wide CLPOB generation] This controls wide CLPOB generation during the vertical OPB period. See the Timing Charts for the actual operation. The default is "OFF". D32 0 1 Description of operation Wide CLPOB generation OFF Wide CLPOB generation ON
Control data: D34 , D35 PTOB [CLPOB waveform pattern] This indicates the CLPOB waveform pattern. The default is "Normal". D35 0 0 1 1 D34 0 1 0 1 Waveform pattern (Normal) (Shifted rearward) (Shifted forward) (Wide)
Control data: D36 , D37 LDAD [ADCLK logic phase] This indicates the ADCLK logic phase adjustment data. The default is "90" relative to MCKO. D37 0 0 1 1 D36 0 1 0 1 Degree of adjustment () 0 90 180 270
Control data: D38 , D39 STB [Standby] The operating mode is switched as follows. However, the standby bits are loaded to the CXD3423GA and control is applied immediately at the rising edge of SEN1. D39 X 0 1 D38 0 1 1 Symbol CAM SLP STB Operating mode Normal operating mode Sleep mode Standby mode
See the Pin Status Table for the pin status in each mode. - 23 -
CXD3423GA
Control data/shutter data: [Electronic shutter] The CXD3423GA realizes various electronic shutter functions by using control data D20 SMD and D21 HTSG 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 D20 SMD. D20 0 1 Description of operation Electronic shutter stopped mode Electronic shutter 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 D29 D28 D27 0 1 0 1 1 D26 D25 D24 D23 1 C 0 0 0 0 1 LSB D22 D21 D20 3 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)
Note) The bit data definition area is assured in terms of the CXD3423GA functions, and does not assure the CCD characteristics. The period during which SVD and SHD are specified together is the shutter speed. An image of the exposure time calculation formula is shown below. In actual operation, the precise exposure time is calculated from the operating frequency, VD and HD periods, decoding value during the horizontal period, and other factors. (Exposure time) = SVD x (1V period) + {(number of HD per 1V) - (SHD + 1)} x (1H period) + (distance from SUB to SG during the readout period) 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). - 24 -

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.

Exposure time
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. - 25 -

Exposure time
[EXP pulse] The ID/EXP pin (Pin N9) output can be switched between the ID pulse or the EXP pulse using D33 EXP. The default is the "ID" pulse. See the Timing Charts for the ID pulse. The EXP pulse indicates the exposure time when it is high. In principle, the transition points are the last SUB pulse falling edge and the readout pulse falling edge, that is to say from the time the charge is completely discharged until transfer ends. However, when the readout pulse timing differs within the same readout portion such as in draft mode, the average value is used. Then, when there is no SUB pulse in the next field, the readout pulse falling edge is defined as the start position, but in this case the transition points overlap and disappear, so a tentative start position is defined. This is shown below. SG [ICX432] Frame mode Draft/AF mode Frame mode Draft mode 1460 1682 A: 1071 B: 1175 1123 Tentative start position 1480 1784 1091 1195 1175

See the EXP pulse indicated in the explanatory diagrams under [Electronic shutter] for an image of operation.

CCD Signal Processor Block Serial Interface Control The CXD3423GA'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 five categories of CCD signal processor block serial interface data: standby control data, PGA gain setting data, OB clamp level setting data, input pulse polarity setting data, and output delay adjustment 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 has been reflected to operation 6 ADCKLI clocks after that, then transmit the next category. When the power supply is set to ON, be sure to initialize for transmitting all category data. The details of each data are described below.

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 pins 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.

t2 t2 t1 -7.5V
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 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. - 53 -
