NOTES
1
Passband Ripple is defined as the 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 at the attenuation point referred to under Note 4.
4
Stopband Attenuation refers to the attenuation point (dB) at the frequency referred to under Note 3.

When used to interface progressive scan systems, the ADV7192
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. All filter plots show the 4 Oversampling
responses.
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 I and II. For
more detailed filter plots refer to Analog Devices’ Application
Note AN-562.
