Color Low-Pass Filter
In some applications, it is desirable to limit the Cb/Cr bandwidth to avoid crosstalk. This is especially true
in the case of video signals that have asymmetrical Cb/Cr sidebands. The provided color LP filters 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 Chrominance Control #2 Register (Section 7.2.27), 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 3-3.

3.5
Luminance Processing
The luma component is derived from the composite signal by subtracting the remodulated chroma
information. A line delay exists in this path to compensate for the line delay in the adaptive comb filter in
the color processing chain. The luma information is then fed into the peaking circuit, which enhances the
high-frequency components of the signal, thus, improving sharpness.
3.6
Chrominance Processing
For NTSC/PAL formats, the color processing begins with a quadrature demodulator. The Cb/Cr signals
then pass through the gain control stage for chroma saturation adjustment. An adaptive comb filter is
applied to the demodulated signals to separate chrominance and eliminate cross-chrominance artifacts.
An automatic color-killer circuit is also included in this block. The color killer suppresses the chrominance
processing when the burst amplitude falls below a programmable threshold (see I2C subaddress 06h,
Section 7.2.7). The SECAM standard is similar to PAL except for the modulation of color, which is FM
instead of QAM.
3.7
Timing Processor
The timing processor is a combination of hardware and software running in the internal microprocessor
that serves to control horizontal lock to the input sync pulse edge, AGC and offset adjustment in the
analog front end, and vertical sync detection.
