S1
Circuit 2
Channel selection pin MSB (binary logic code). This pin does not have internal pull-up or
pull-down resistors.
15
S0
Circuit 2
Channel selection pin. LSB (binary logic code). This pin does not have internal pull-up or
pull-down resistors.
16
CLAMP
Circuit 2
Clamp/Store Logic Input. Logic ‘0’ selects the clamp DC restore state, logic ‘1’ selects the
hold state. This pin does not have internal pull-up or pull-down resistors.
18
GOUT
Circuit 3
Green/Luma Output
19
REF_G
Green/Luma Reference. Green/Luma channel offset by this voltage during DC restore
state. Reference voltage range is 0 to +3.0V.
21
BOUT
Circuit 3
Blue Output
23
REF_RB
Red and Blue Reference. Red and blue channels offset by this voltage during DC restore
state. Reference voltage range is 0 to +3.0V.
24
ROUT
Circuit 3
Red Output
25
AV2
Circuit 2
Gain Set. Set to logic high for gain of x2 (+6dB), or set to logic low for a gain of x1 (+0dB). If
left floating, an internal pull-down resistor pulls this pin low (300k
Ω pull-down).
