Note 1: VIN
PP is the signal swing before the external capacitor tied to the MUX inputs.
Note 2: The -0.1V minimum is specified in order to accommodate black level signals lower than the external DC
reference (clamp) voltage.
Note 3: The V
DCEXT-0.1V minimum is specified in order to accommodate black level signals lower than the external DC
reference voltage.
