Description of Functions 1. Progressive Scan CCD drive pulse generation * Combining this IC with a crystal oscillator generates a fundamental frequency of 40.49MHz. * CCD drive pulse generation is synchronized with the HD and VD inputs. * Setting the RM pin to low sets the frame rate to double-speed readout mode (24 frames/s). However, the CCD vertical resolution is halved. * fCL = 1616fHD, fHD = 1044fVD (normal readout mode: RM = high) * fCL = 1616fHD, fHD = 522fVD (double-speed readout mode: RM = low) * The various operations are performed by the TRIG and ESG inputs. (See the following items.)
CL 1 HD 65 68
XH1
Detection timing for VD, RM, TRIG and ESG
After HD input is detected, VD, RM, TRIG and ESG are detected at the rising edge of the 65th CL pulse. However, the low level period for each pulse should be set to 1H or longer to prevent misoperation.
2. Electronic shutter The electronic shutter has the following four shutter modes. * Electronic shutter off: Exposure time is 1/12s (RM = high) or 1/24s (RM = low) * High-speed electronic shutter: Exposure time is shorter than 1/12s (RM = high) or 1/24s (RM = low) * Low-speed electronic shutter: Exposure time is longer than 1/12s (RM = high) or 1/24s (RM = low) The shutter speed is set serially using the STRB, DCLK and DATA pins. The electronic shutter mode and the meanings of the numbers indicated by D0 to 10 vary according to the SMD1 and SMD2 settings of the internal register.

1 When RM = high. 1/24s accumulation when RM = low. 2 Relationship between the number of exposed lines and the exposure time The relationship between the number of exposed lines and the exposure time is as follows. (Exposure time) = (Number of exposed lines) x (One horizontal scan period) + (Accumulation time for the readout lines) In this formula, one horizontal scan period equals the HD falling interval, and the accumulation time for the readout lines is the time from the rising edge of XSUB to the falling edge of XSG (510 bits). Also, the number of exposed lines should be set to greater than 1 but less than 1043. 3 The number of exposed frames should be set to greater than 1 but less than 120. During external trigger mode, the number of exposed frames should be set to greater than 2. Timing Chart

3. External trigger mode External trigger mode starts exposure in sync with the external trigger input. No special pins are required to set this mode. Note that during external trigger mode, normal readout mode results regardless of the RM status. The IC prepares to shift to external trigger mode with the rising edge of the TRIG pin.1 The timing to shift to external trigger mode varies according to the mode setting. (See the table.) The BUSY pin maintains high status during external trigger mode. Whether or not to discharge the vertical CCD charge is set by FSE just after shifting to external trigger mode. 1 See the detection timing for VD, TRIG and ESG. Mode settings during external trigger SMD1 L L H H SMD2 L H L H Description of operation Trigger input is not accepted. Fix SMDE to high. The IC is shifted to external trigger mode by HD, exposure is finished after the set time, and XSG is output.2 The IC is shifted to external trigger mode by VD and exposure is finished in sync with VD after the set time.2 Trigger input is not accepted. Fix SMDE to high
2 The exposure time setting method is the same as the exposure time setting for the electronic shutter. During external trigger mode, the previously exposed signal charge sometimes remains in the vertical CCD when exposure finishes. In this case, the image shot with external trigger mode is output overlapped with the previously shot image. Setting FSE to high performs discharge operation for signal charges remaining in the vertical CCD after trigger input. Discharge operation is not performed when FSE is low. This setting is only valid when using the highspeed shutter. During external trigger mode, exposure can be finished in sync with the falling edge of ESG.3 If SMDE is set to low, the XSG pulse is output regardless of the electronic shutter setting, when the falling edge of ESG is detected. ESG should be fixed to high status at all times other than during external trigger mode. 3 See the detection timing for VD, TRIG and ESG. After high-speed external trigger mode is finished, the exposure time differs from that performed by the electronic shutter setting. This is because the start and finish of external trigger mode are not synchronized to VD input. 4. Internal logic stop (standby mode) When the STDBY pin is set to low, clock supply is stopped to a part of the internal logic. However, output from the oscillation cell (OSCI and OSCO pins) as well as the CL and CKO pins does not stop. The status of each output pin when STDBY is low is shown below.

When using CH pin at high, leave XSHP2, XSHD2, XRS2 and CLD2 pins open, respectivery. * XSHP, XSHD, XRS and CLD pins operate as shown in the figure below.
