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 (0.1µF 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.

Timing Generator Block Serial Interface Control  
The CXD3408GA'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.

Draft mode is the pulse eliminator drive mode called octuple speed mode in the ICX406. This is a high frame  
rate drive mode that can be used for purposes such as monitoring and auto focus (AF).  
AF1 and AF2 modes are the pulse eliminator drive modes called by the same names in the ICX406. These  
drive modes are based on draft mode, and are used to increase the frame rate for auto focus (AF). In these  
modes, the screen is swept in the vertical direction and the center portion lines are cut out.  
Frame mode is the ICX406 drive mode in which the data for all lines are read. This drive mode is comprised of  
A and B Fields, so when it is established, repeated drive is performed in the manner of A B A and so  
on.  
Frame mode (A or B Field) is the drive mode in which each field can be specified separately.  
Control data: D17 NTPL [SSG function switching]

[Electronic shutter stopped mode]

SHD  
SPL  
Note) The bit data definition area is assured in terms of the CXD3408GA 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 + {(number of HD per 1V) (SHD + 1)}  
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).

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.

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.

The ID/EXP pin (N9) output can be switched between the ID pulse or the EXP pulse using D33 EXP. The

when it is high. The transition point is the last SUB pulse falling edge, and midpoint value (1338ck) of each  
V1A/B and V3A/B ternary out put falling edge. When there is no SUB pulse, the later ternary output falling  
edge (1416ck) is used. See the EXP pulse indicated in the explanatory diagrams under [Electronic shutter] for  
an image of operation.  
Note that the above specification is based on draft mode. For frame mode, the former value is 1260ck and the  
latter value is 1416ck.

CCD Signal Processor Block Serial Interface Control  
The CXD3408GA'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 ADCLKI clocks after that has been reflected to operation, then  
transmit the next category.

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.

0V  
20%  
t2  
7.5V  
t2 t1  
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.
