V
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.
V
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.
The voltage of this pin is detected and the
status is returned to the I
functions, S4 or S8. It is used for detecting
whether the 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, 3 or 4 registers.
Cb, B or C input pin.
Input the signal via a capacitor.
