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 36 and Figure 37.
If SD Luma SSAF gain is enabled (Subaddress 0x87, Bit 4), there
are 13 response options in the range 4 dB to +4 dB. The desired
response can be programmed using Subaddress 0xA2. The
variation of frequency responses are shown in Figure 33 to
Figure 35.
In addition to the chroma filters listed in Table 38, the ADV739x
contains 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 67).
This filter can be controlled with Subaddress 0x82, Bit 0.

If this filter is disabled, one of the chroma filters shown in
Table 39 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.

3 dB bandwidth refers to the 3 dB cutoff frequency.
