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 CXD2498R 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: D34 to D35 PTOB [OBCLP waveform pattern] This specifies the OBCLP waveform pattern. The default is "Normal". See the Timing Charts for details. D35 0 0 1 1 D34 0 1 0 1 Waveform pattern (Normal) (Rearward) (Forward) (Wide)

CXD2498R
Control data: [Drive mode] The CXD2498R realizes various drive modes by using control data D10 to D11 MODE and D16 to D17 PTMD. The drive mode bits are loaded to the CXD2498R and reflected at the falling edge of VD. These details are described below. First, the basic drive mode is assigned using the control data D10 to D11 MODE. D11 0 0 1 1 D10 0 1 0 1 Description of operation Draft mode (default) Progressive scan mode Double speed mode Frame mode
Draft mode is the pulse eliminator drive mode called octuple speed mode in the ICX282. This is a high frame rate drive mode that can be used for purposes such as monitoring and auto focus (AF). Progressive scan mode is the pulse eliminator drive mode called double speed mode (1) in the ICX282. Pulse elimination is performed, but the frame data is obtained over one field period and corresponds to progressive scan drive, so it is called progressive scan mode in this data sheet. Double speed mode is the pulse eliminator drive mode called double speed mode (2) in the ICX282. Readout is applied with two lines added to provide an image which appears like frame mode with an increased frame rate. 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 is the ICX282 drive mode in which the data for all lines are read. This drive mode is also 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 like double speed mode. [Special drive modes] Of the above basic drive modes, when a drive mode other than double speed mode is specified, special drive modes can be specified using the control data D16 to D17 PTMD.

See the Timing Charts for details of all drive modes. Note that center scan modes (3) and (4) in the ICX282 correspond to center scan 1 and 2 in frame mode, and center scan modes (1) and (2) in the ICX282 correspond to center scan 1 and 2 in progressive scan mode.

CXD2498R
Control data/shutter data: [Electronic shutter] The CXD2498R realizes various electronic shutter functions by using control data D13 SMD and D14 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 D13 SMD. D13 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 D30 X 0 1 LSB D23 D22 D21 D20 0 0 3 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. [Electronic 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 CXD2498R 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). - 20 -

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] This mode controls the V1A/B/C and V3A/B/C ternary level outputs (readout pulse block) using D14 HTSG. When control is applied, V pulse modulation does not occur during the readout period, and only normal V transfer is performed.

Exposure time
[EXP pulse] The ID/EXP pin (Pin 4) 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. The transition point is midpoint value (1515ck) of the last SUB pulse falling edge and each V1A/ B/C and V3A/B/C ternary output falling edge. When there is no SUB pulse, the later ternary output falling edge (1590ck) is used. See the EXP pulse indicated in the explanatory diagrams under [Electronic shutter] for an image of operation.

The HD of this chart indicates the actual CXD2498R load timing. The numbers at the output pulse transition points indicate the count at the MCKO rise from the fall of HD. The HD fall period should be between approximately 2.8 to 12.0s (when the drive frequency is 22.5MHz). This chart shows an period of 115ck (5.1s). Internal SSG is at this timing. SUB is output at the timing shown above when output is controlled by the serial interface data. High-speed sweep of V1A/B/C, V2, V3A/B/C and V4 is performed up to 7H 2848ck (#285) in draft mode (AF1), 11H 2184ck (#421) in draft mode (AF2).
