I / O
INTERFACE CIRCUIT
1
AVSS
Ground for analog components.
—
2
VRB
ADC bias lower limit reference voltage.
This defaults internally to approximately
2.25 V, so this pin should normally be
conected to ground (AVSS) through a
0.01 F capacitor.
3
VRT
ADC bias higher limit reference voltage.
This defaults internally to approximately
2.8 V, so this pin should normally be
conected to ground (AVSS) through a
0.01 F capacitor.
4
ADIN
Composite video signal input.
I
5
BIAS1
ADC bias voltage.
This defaults internally to approximately
1.3 V, so this pin should normally be
conected to ground (AVSS) through a
0.01 F capacitor.
6
TEST
Test terminal. Normally connected to
ground (DVSS).
7
KILLER
This pin is switch for color killer circuit.
H : For B / W signal, Y / C separation
OFF.
L : Normal Y / C separation
I
