SD Internal Filter Response
Subaddress 0x80, Bits[7:2]; Subaddress 0x82, 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 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 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 in
frequency responses is shown in Figure 35 to Figure 37.
In addition to the chroma filters listed in Table 44, the ADV7342/
ADV7343 contain 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 65). This filter can be controlled with Subaddress
0x82, Bit 0.
