The CXD2452R basically loads and reflects the serial interface data sent in the above format in the readout portion at the falling edge of HRI. Here, readout portion specifies the horizontal interval during which XSG1 rises. There are two types of serial interface data: drive control data and phase adjustment data. Hereafter, these data are distinguished by referring to the former as control data and the latter as adjustment data. An example of the initialization data for the CXD2452R control data is shown below. This data is based on the Application Circuit Block Diagram, so care should be taken as there are some differences from the RST pin initialization data. Concretely, the internal SSG operates, the XCLPOB and ID pulses are generated, and the 3/2 MCK pulse is stopped. This data shows the values when the EBCKSM pin is low and D64 to D71 CHKSUM is valid.

The adjustment data does not normally need to be set. However, when adjustment is difficult due to the system configuration or for other reasons, the data considered most appropriate at that time should be set as the initialization data.

CXD2452R
Detailed Description of Each Data D00 to D07 CHIP The serial interface data is loaded to the CXD2452R when D00 and D07 are 1. However, this assumes that either the EBCKSM pin is low and D64 to D71 CHKSUM is satisfied or the EBCKSM pin is high. MSB D07 D06 1 0 LSB D00 1 Function Loading to the CXD2452R

Note that when SEN is shared with other ICs and indentification is performed using CHIP-ID, the CXD2452R data must be positioned immeditately before the load timing, that is to say at the very end.
D08 to D15 CTGRY Of the data provided to the CXD2452R by the serial interface, the CXD2452R loads D16 and subsequent data to the control register side when D08 is 0, and to the adjustment register side when D08 is 1. However, this assumes that the CXD2452R is selected by CHIP and that either the EBCKSM pin is low and D64 to D71 CHKSUM is satisfied or the EBCKSM pin is high.

Note that the CXD2452R cannot apply both categories simultaneously during the same vertical interval. Also, care should be taken as the data is overwritten even if the same category is applied.
D16 to D35 Electronic shutter mode The CXD2452R's electronic shutter mode can be switched as follows by SMD D16 to D17 . Handling of the data from D18 to D35 differs according to the mode, and is explained in detail below. D17 X 0 1 D16 0 1 1 Description of operation XSUB stopped mode High-speed/low-speed shutter mode HTSG control mode
The electronic shutter data is expressed as shown in the table below using Shut.HD as an example. MSB D35 0 1 D34 1 D33 1 D32 1 C D31 0 D30 0 D29 0 D28 0 3 D27 1 LSB D26 1 Shut.HD is expressed as 1C3h .
[XSUB stopped mode] During this mode, the data from D18 to D35 is invalid. The shutter speed is 1/60s during monitoring drive mode, and 1/30s during recording drive mode. - 13 -
CXD2452R
[High-speed/low-speed shutter mode] During this mode, the data has the following meanings. Symbol Shut.FRM Shut.HD Data D18 to D25 D26 to D35 Description Shutter speed data (number of vertical intervals) specification Shutter speed data (number of horizontal intervals) specification
The CXD2452R does not distinguish between the high-speed shutter and low-speed shutter modes. The interval during which Shut.FRM and Shut.HD are specified together is the shutter speed. At this time, Shut.FRM controls the XSG1, XSG2 output, and Shut.HD controls the XSUB output. Concretely, when specifying high-speed shutter, Shut.FRM is set to 00h. (See the figure.) During low-speed shutter, or in other words when Shut.FRM is set to 01h or higher, the serial interface data is not loaded until this interval is finished. However, care should be taken as the vertical interval indicated here is set in 1/60s units when the drive mode is monitoring drive mode and 1/30s units during recording drive mode. For monitoring drive mode, care should be taken that shut.HD value is offset. This is because the same exposure time can be obtained for the same shut.HD data without depending on drive mode basically for highspeed shutter. Formula for calculating the electronic shutter speed: [Shut.FRM/Shut.HD] (unit: s) Monitoring drive mode: T = Shut.FRM1.66834104 + {(20Ch - Shut.HD)780 + 447} 81.510-3 (107h Shut.HD 20Ch)

[HTSG control mode] During this mode, the data from D18 to D35 is invalid. The shutter speed is the value obtained by adding the shutter speed specified in the preceding vertical interval to the vertical period during which XSG1 (and XSG2) is stopped as shown in the figure.

D48 EXPOSE 0: No operation 1: XSUB for recording exposure is generated. This control specification is such that one XSUB pulse is always generated during the horizontal interval immediately following the readout portion even if the electronic shutter speed is set to 1/60s (SMD = 00). This mode is closely related to D51 PSMT, so see D51 regarding the control.
D51 PSMT 0: Driving is controlled in accordance with monitoring drive mode under the assumption that vertical/horizontal sync signals are input. 1: Driving is controlled in accordance with recording drive mode under the assumption that vertical/horizontal sync signals are input. See the timing charts for the vertical/horizontal sync signals in accordance with each mode. Note that when switching from monitoring drive to recording drive mode, the pixels decimated thus far must be cleaned. Concretely, this operation is supported by generating XSUB, but the CXD2452R facilitates this control by using D48 EXPOSE. (See the figure.)

D60 to D61 DSG The CXD2452R can stop control to the CCD pulses and pulses for the sample-and-hold and analog/digital conversion ICs by setting the DSGAT pin low. Conversely, when the DSGAT pin is set high, the controlled pulses can be switched as follows using the serial interface data. D61 0 0 1 1 D60 0 1 0 1 No control performed CCD pulse control Sample-and-hold and analog/digital conversion IC pulse control CCD pulse and sample-and-hold and analog/digital conversion IC pulse control Operating mode
Here, CCD pulses refer to the H1, H2, RG, XV1, XV2, XV3, XSUB, XSG1 and XSG2 pulses. Sample-and-hold and analog/digital conversion IC pulses refer to the XSHP, XSHD, XRS, PBLK, XCLPOB, XCLPDM and CLD pulses. See 7) Output timing characteristics using DSGAT of "AC Characteristics" for the stop control status of each pulse.

The number of XSUB pulses is determined by the serial interface data. This chart shows the case where Shut.HD = 20Ch and XSUB pulses are generated over the entire horizontal interval. In addition to the phase relationship between FRI and HRI shown above, the phases may also be offset by 1/2 horizontal interval. In any case, the readout interval is the 9th HRI fall counted
from the fall of FRI. Note that R and B of CCDOUT indicate lines containing these components, and do not mean the lead pixel component of that line.

The HRI fall interval should be between 3.6 to 9.4s. This chart shows an interval of 78ck (6.3s). XSUB is output at the timing shown above when specified by the serial interface data. The ID transition timing is synchronized with the fall of XV3. WEN is output during the horizontal interval shown in Chart-1. The transition timing is the same as that for ID. R, G and B of H1 indicate the output pixel color. In addition to the lines starting from R and G shown above, there are also lines starting from G and B.
The HRI of this chart is equivalent to HRI' of Chart-7. This HRI indicates a timing that the CXD2452R takes in actually. The numbers at the output pulse transition points indicate the count at the MCK (780fH) rise from the fall of HRI.
