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 atten-
uation, 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 38 and Figure 39.
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. Variation
in frequency responses is shown in Figure 35 to Figure 37.
In addition to the chroma filters listed in Table 43, the ADV739x
contains an SSAF filter that is 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 69). This filter can be controlled with Bit 0 of Sub-
address 0x82, Bit 0.

If this filter is disabled, one of the chroma filters shown in
Table 44 can be selected and used for the CVBS or luma/
chroma signal.

pass band, measured in decibels. 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.
Pass-band ripple is the maximum fluctuation from the 0 dB response in the
3 dB bandwidth refers to the −3 dB cutoff frequency.
