FUNCTION
Power-Supply Input
Frequency-Select Input. LSB for bandwidth selection.
Video Input Channel 1
Video Input Channel 2
Video Input Channel 3
BIAS
Bias Control Digital Input. Enables voltage bias for the Pb/B and Pr/R channels. Force BIAS low to
enable voltage bias and disable the input clamps. Force BIAS high to disable voltage bias and enable
the input clamps.
N.C.
GND
No Connection. Not internally connected.
Ground
SHDN
Shutdown Digital Input. SHDN places the device into a powered-down state. Force SHDN low to enable
shutdown. Force SHDN high for normal operation.
