Serial Interface Control The CXD2497R basically loads and reflects the 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.

CXD2497R
Detailed Description of Each Data Shared data: D08 to D09 CTG [Category] Of the data provided to the CXD2497R by the serial interface, the CXD2497R loads D10 and subsequent data to each data register as shown in the table below according to the combination of D08 and D09 . D09 0 0 1 D08 0 1 X Description of operation Loading to control data register Loading to shutter data register Test mode
Note that the CXD2497R 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: D10 to D12 MODE [Drive mode] The CXD2497R drive mode can be switched as follows. However, the drive mode bits are loaded to the CXD2497R and reflected at the falling edge of VD.

CXD2497R
Control data: [AF drive] The CXD2497R controls the drive of the vertical cut-out area of 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 this mode cannot support operation such as electrical image stabilization. AF drive bits are loaded to the CXD2497R 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 of 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 sweeps are different according to the selected mode. It is 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 D21 1 6 1 D20 0 D19 D18 1 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)

CXD2497R
Control data/shutter data: [Electronic shutter] The CXD2497R 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 dummy on this IC. MSB D31 X D30 0 1 D29 0 D28 1 D27 1 D26 1 C D25 0 D24 0 D23 D22 0 0 3 LSB D21 D20 1 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 by the conditions during low-speed shutter. Note) The bit data definition area is assured in terms of the CXD2497R functions, and does not assure the CCD characteristics. - 19 -

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.

[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.

The number of SUB pulses is determined by the serial interface. This chart shows the case where SUB pulses are output in each horizontal period. ID is low for lines where CCD OUT contains the R component, and high for lines where CCD OUT contains the B component. VD of this chart is NTSC equivalent pattern (918H + 1716ck units). For PAL equivalent pattern, it is 945H units, but 1208ck period as for 944H and 945H.
