Description

Ground for all circuits other than RGB,

composite video and Y/C output circuits.

The leads to GND2 should be as short and

wide as possible.

Analog RGB signal inputs. Input at

100% = 1Vp-p (max.). To minimize clamp

error, input at as low impedance as

possible.

ICLP turns ON only in the burst flag period.
