NOTES
1Passband Ripple is dened to be fluctuations from the 0 dB response in the passband, measured in (dB). The
passband is dened to have 0–fc frequency limits for a low-pass lter, 0–f1 and f2–innity for a notch lter,
where fc, f1, f2 are the –3 dB points.
23 dB bandwidth refers to the –3 dB cutoff frequency.

NOTES
1Passband Ripple is dened to be fluctuations from the 0 dB response in the passband, measured in (dB). The
passband is dened to have 0–fc frequency limits for a low-pass lter, 0–f1 and f2–innity for a notch lter,
where fc, f1, f2 are the –3 dB points.
23 dB bandwidth refers to the –3 dB cutoff frequency.
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 lters
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 ve low-pass
responses, a CIF response and a QCIF response, as can be seen in
the following gures.
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
2C. 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.
