Multistandard video decoder with adaptive comb filter
8.1.1.1
Clamping
The clamp control circuit controls the correct clamping of the analog input signals. The
coupling capacitor is also used to store and filter the clamping voltage. An internal digital
clamp comparator generates the information with respect to clamp-up or clamp-down.
The clamping levels for the four ADC channels are fixed for luminance (120),
chrominance (256) and for component inputs as component Y (32), components P
B
and
P
R
(256) or components RGB (32). Clamping time in normal use is set with the HCL pulse
on the back porch of the video signal.
