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 PrPb
filter supports several different frequency responses, including
six low-pass responses, a CIF response, and a QCIF response, as
shown in Figure 39 and Figure 40.
If SD SSAF gain is enabled (Subaddress 0x87, Bit 4), there are 13
response options in the 4 dB to +4 dB range. The desired response
can be programmed using Subaddress 0xA2. The variation of
frequency responses is shown in Figure 36 to Figure 38.
In addition to the chroma filters listed in Table 39, the ADV7342/
ADV7343 contain an SSAF filter specifically designed for the color
difference component outputs, Pr and Pb. This filter has a cutoff
frequency of ~2.7 MHz and a gain of –40 dB at 3.8 MHz (see
Figure 65). This filter can be controlled with Subaddress 0x82,
Bit
0.

If this filter is disabled, one of the chroma filters shown in
Table 40 can be selected and used for the CVBS or luma/
chroma signal.

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, and 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.
