If the input to the external capacitor has a source
impedance (R

This value corresponds to the black reference of the
image sensor. When the CLAMP pin is set back to low,
the ADC samples the video signal with respect to the
black reference. The typical value for the external
capacitor is 100pF. This value should be adjusted
according to the time constant (Tc) needed in a particu-
lar application. The CLAMP pin has an internal 150
ohm impedance (R
INT
) which is in series with the
external capacitor (C
EXT
).
