Description

Clamp pulse output; Open collector-

type pin at positive polarity.

Clamp pulse output; Open collector-

type pin at negative polarity.

Selects output position of a clamp

pulse. Input at TTL level.

When Low level is selected, a clamp

pulse is output at a back porch

interval.

When High level is selected, clamp

pulse is output at a sync interval.

See the Description of Operation for

Input/Output Matrix.

Output polarity information of

horizontal and vertical sync signals.

See the Description of Operation for

Input/Output Matrix.

HD (H. Drive Pulse) output; Push-pull

type pin at positive polarity.

Composite sync or sync signal

separated from video sync is output.

Output is at positive polarity.

Input for V. sync separator

comparator. Integrates the output at

Pin 19 and inputs it.
