SD Internal Filter Response
[Subaddress 40h; Subaddress 42, Bit 0]
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 six low-pass responses, a CIF
response, and a QCIF response, as can be seen in the figures on
the following pages.
If SD SSAF gain is enabled, there is the option of 12 responses
in the range from –4 dB to +4 dB [Subaddress 47, Bit 4]. The
desired response can be chosen by the user by programming the
correct value via the I
2
C [Subaddress 62h]. The variation of fre-
quency responses can be seen in the figures on the following pages.
In addition to the chroma filters listed in Table VII, the
ADV7312 contains an SSAF filter specifically designed for and
applicable to the color difference component outputs, U and V.
This filter has a cutoff frequency of about 2.7 MHz and –40 dB
at 3.8 MHz, as can be seen in Figure 37. This filter can be
controlled with Address 42h, Bit 0.
If this filter is disabled, the selectable chroma filters shown in
Table VII can be used for the CVBS or Luma/Chroma signal.

NOTES
1
Pass-band ripple is the maximum fluctuation from the 0 dB response in the
pass band, measured in dB. The pass band is defined to have 0 Hz to fc (Hz)
frequency limits for a low-pass filter, 0 Hz to f1 (Hz) and f2 (Hz) to infinity for
a notch filter, where fc, f1, and f2 are the –3 dB points.
2
3 dB bandwidth refers to the –3 dB cutoff frequency.
