DESCRIPTION
A pulse to clamp the optical black signal.
This pulse is controlled by serial data BCPCNT.
BCPCNT = H; This pulse stays high during the
absence of effective pixels within the
vertical blanking or during the
sweepout signal.
BCPCNT = L; This pulse stays high during the
sweepout signal.
A pulse to clamp the dummy outputs of the CCD signal.
This pulse stays high during the sweepout period.
An output pin for AD converter. The output phase of
ADCK is selected by serial data in 90˚ steps.
A pulse to clamp the feed-through level for the CCD.
The output phase and output polarity of FCDS are
selected by serial data.
A pulse to sample-hold the signal for the CCD.
The output phase and output polarity of FS are selected
by serial data.
A trigger pulse for effective signal period.
The pulse is used in the color separator.
The signal switches between high and low at every line.
Supply of +3.3 V power.
Supply of +3.3 V power.
A grounding pin.
An input pin for reference clock oscillation.
The frequency is 49.0909 MHz.
An output pin for reference oscillation.
The output is the inverse of CKI (pin 26).
An output pin to generate HD and VD pulses.
The frequency is 24.54545 MHz.
An output pin for DSP IC. The frequency is 24.54545 MHz.
The output phase of DCLK is selected by serial data in
90˚ steps.
An input pin for reference of vertical pulse.
Connect to VD pin of DSP IC.
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 LR38620. For details, see "Serial Data Control".
An input pin for the clock of the shift register, to control
the functions of LR38620. For details, see "Serial Data
Control".
