•CCD signal input

•CCD signal must be input through

a capacitor.

•The capacitor should preferably be

0.022µF.

•2.6V typ. bias voltage

•Supply voltage

•Sample-hold pulse input

•Active high

•1.5V threshold voltage

•Sampling pulses are input in syn-

chronization with the video timing

of CCD signal at Pine.
