OFDX

O3MR1

OFD pulse output

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.

O3MR1

Vertical transfer

pulse output 1

A vertical transfer pulse for the CCD.

O3MR1

PBLK

O3MR1

Pre-blanking pulse

output

A pulse for pre-blanking. This pulse is controlled by

serial data BLKCNT.

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.
