Pin Name Pin No.
Description
Chrominance full scale current control. As with the LUMAGAIN pin, a resistor between this pin and GND
CHROMAGAIN
39
controls the magnitude of the chrominance video signal. An internal loop amplifier adjusts a reference current
flowing through this resistor so that the voltage across it is equal to the Vref voltage. This reference current
has a weighting equal to 16 LSB’s.
TEST0-TEST7 41-48 These pins must be held low.
CTRLC1
CTRLC2
