NOTES
1
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.
2
3 dB bandwidth refers to the –3 dB cutoff frequency.
3
Stopband Cutoff refers to the frequency of the attenuation point referred to in Note 4.
4
Stopband Attenuation refers to the attenuation point (dB) of the frequency referred to in Note 3.

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.
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
2
C. The
variation of frequency responses can be seen in the tables on
the following pages.
For a more detailed filter specification, refer to Analog Devices’
application note AN-562.
