2.1.3
A/D Converters
The TVP5022 contains two 8-bit A/D converters which digitize the analog video signal inputs. To prevent
high frequencies which are above half of the sampling rate from entering into the system, video inputs may
require external anti-aliasing low pass filters.
2.2
Digital Processing
Figure 2–2 is a block diagram of the TVP5022 digital video processing. This block receives digitized
composite or S-video signals from the A/D converters, and performs Y/C separation, chroma demodulation,
and Y-signal enhancements. It also generates the horizontal and vertical syncs. The YUV digital output may
be programmed into various formats: 16-bit or 8-bit 4:2:2, 12-bit 4:1:1 and ITU-R BT.656 parallel interface
standard. The circuit uses comb filters to reduce the cross-chroma and cross-luma noise.
