Equivalent circuit
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.
Subcarrier input.
Input 0.4 to 0.5Vp-p sine wave or pulse.
Refer to Notes on Operation, Nos. 3 and 5.
Pin for switching between NTSC and PAL
modes
NTSC: VCC, PAL: GND
BF pulse monitoring output. Incapable of
driving a 75
Ω load.
Analog RGB signal inputs. Input
100%, = 1Vp-p (max.). To minimize clamp
error, input at as low impedance as
possible.
ICLP turns ON only in the burst flag period.
