2 Functional Description
2.1
Analog Video Processing and A/D Converters
Figure 2
1 shows a functional diagram of the analog video preprocessors and A/D converters. This block provides
the analog interface to all video inputs. It accepts up to six inputs and performs source selection, video clamping, video
amplification, analog-to-digital conversion, and fine gain and offset adjustments to center the digitized video signal.
In a component mode, three YUV input signals are digitized by two A/D converters applying color multiplexing of UV.
Using a single A/D channel for UV chroma avoids gain mismatch between color components.
