Supply power through a resistor from pin 11
as in the Application Circuit. This pin voltage
is clipped to 3.3 V (typ.) by the internal
regulator.
GND pin for the logical circuits.

Connect 5.0 V (typ.)
GND pin for the sync and video circuits.
V
Connect 9.0 V (typ.)
GND pin for the audio circuits.
CVBS or Y input pin.
Input the CVBS or Y signal in NTSC, PAL or
SECAM via a clamp capacitor.
Chroma signal input pin.
Input C signal via a capacitor.
This pin’s voltage is detected and the status
is returned to I
S6. It is used for detecting whether S-pin is
connected or not.
Y, G or CVBS input pin.
Input the signal via a clamp capacitor.
The clamp system is selectable by
CLAMP1, 2 or 3 registers.
Cb, B or C input pin.
Input the signal via a capacitor.
