INTERNAL FILTER RESPONSE
The Y Filter supports several different frequency responses,
including two low-pass responses, two notch responses, an Ex-
tended (SSAF) response with or without gain boost/attenuation, a
CIF response and a QCIF response. The UV Filter supports
several different frequency responses, including four low-pass
responses, a CIF response and a QCIF response. These can be
seen in Figures 4 to 18.
In Extended Mode there is the option of twelve 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
Figures 19 to 21.
