Cautions 1. The clamp circuit is not necessary when the sync-chip level (1 V DC) can be directly input

to pin 24.

2. Pin 20 is connected so as to reject unwanted radiation.

3. This application circuit is assumed to input 2Vp-p video signals.

4. Connect pin 9 to GND or VDD (do not open). Pin 10 should be open.
