Color Low-Pass Filter
In some applications, it is desirable to limit the Cb/Cr bandwidth to avoid crosstalk. This is especially true
in case of video signals that have asymmetrical Cb/Cr sidebands. The color LP filters provided limit the
bandwidth of the Cb/Cr signals.
Color LP filters are needed when the comb filtering turns off, due to extreme color transitions in the input
image. See Section 3.21.25, Chrominance Control #2 Register, for the response of these filters. The filters
have three options that allow three different frequency responses based on the color frequency
characteristics of the input video as shown in Figure 3-4.
