DESCRIPTION
A pulse to clamp the feed-through level from CCD.
The output phase of FCDS is selected by serial data.
A pulse to sample-hold the signal from CCD.
The output phase of FS is selected by serial data.
Supply of +3.3 V power.
An input pin for resetting all internal circuits at power on.
Connect to VDD through the diode and GND through the
capacitor.
A pulse to sample-hold the signal.
The output phase of RS is selected by serial data.
A grounding pin.
An input pin to control internal vertical clock for long
shutter speed.
H level or open : VD
L level
: VD is masked by the pulse which
is latched at the rising edge of VD.
It's necessary to be set SMD = high and number of the
fields data n ≥ 2 in serial data control at VCON operation.
An input pin for reference clock oscillation.
The frequency is 24.54545 MHz.
An output pin for reference clock oscillation.
The output is the inverse of CKI (pin 25).
An output pin to generate HD and VD pulses.
The frequency is 12.72737 MHz.
An output pin for DSP IC. The frequency is 12.72727 MHz.
The output phase of DCLK is selected by serial data
step by 90˚.
An input pin for reference of vertical pulse.
Connect to VD pin of DSP IC.
Supply of +3.3 V power.
A grounding pin.
An input pin for reference of horizontal pulse.
Connect to HD pin of DSP IC.
An input pin for the strobe pulse, to control the functions
of LR38574. For details, see "Serial Data Control".
An input pin for the clock of the shift register, to control
the functions of LR38574. For details, see "Serial Data
Control".
