DESCRIPTION
A grounding pin.
A pulse to control OFD voltage.
A pulse that sweeps the charge of the photo-diode for
the electronic shutter. Connect to OFD pin of the CCD
through the vertical driver IC and DC offset circuit.
Held at H level in normal mode.

Supply of +3.3 V power.
Supply of +3.3 V power.
A pulse for pre-blanking. This pulse is controlled by
serial data BLKCNT.
Pre-blanking pulse
output
BLKCNT = H; This pulse stays low during the
absence of effective pixels within the
vertical blanking or during the
sweepout signal.
BLKCNT = L; Continuous pulse
The output phase of PBLK is selected by serial data.
