When used to interface progressive scan systems, the ADV7194
allows input to YCrCb signals in Progressive Scan format (3 × 10
bit) before these signals are routed to the interpolation filters
and the DACs.
INTERNAL FILTER RESPONSE
The Y Filter supports several different frequency responses
including two low-pass responses, two notch responses, an
Extended (SSAF) response with or without gain boost/attenuation,
a CIF response and a QCIF response. The UV Filter supports
several different frequency responses including five low-pass
responses, a CIF response and a QCIF response, as can be seen in
the following figures.

Passband Ripple is defined to be fluctuations from the 0 dB response in the passband, measured in (dB). The
passband is defined to have 0–fc frequency limits for a low-pass filter, 0–f1 and f2–infinity for a notch filter,
where fc, f1, f2 are the –3 dB points.
3 dB bandwidth refers to the –3 dB cutoff frequency.

In Extended Mode there is the option of 12 responses in the
range from –4 dB to +4 dB. The desired response can be chosen
by the user by programming the correct value via the I
variation of frequency responses can be seen in the tables on
the following pages.
