OBCP
O4MA3
Optical black clamp
pulse output
A pulse to clamp the optical black signal. This pulse stays
low during the absence of effective pixels within the vertical
blanking. The polarity can be changed by PLCH (pin 39).
A pulse to clamp the AD input signal. The polarity can
be changed by PLCH (pin 39).
A pulse that corresponds to the cease period of the
horizontal transfer pulse.
A pulse to sample-hold the signal from CCD.
The polarity can be changed by PLCH (pin 39).
The output phase of FS is selected by serial data.
A pulse to clamp the feed-through level from CCD.
The polarity can be changed by PLCH (pin 39).
The output phase of FCDS is selected by serial data.
A pulse to sample-hold the signal from CDS circuit.
The polarity can be changed by PLCH (pin 39).
The output phase of RS is selected by serial data.
A grounding pin.
Supply of +3.3 V power.
