14.11.VPC3230D
14.11.1.General Description
The VPC 323xD is a high-quality, single -chip video front -end, which is targeted for 4:3 and 16:9, 50/60 -
Hz and 100/120 Hz TV sets. It can be combined with other members of the DIGIT3000 IC family (such
as DDP 331x) and/or it can be used with 3rd -party products. The main fea tures of the VPC 323xD are;
- high-performance adaptive 4H comb filter Y/C separator with adjustable vertical peaking
- multi-standard color decoder PAL/NTSC/SECAM including all substandards
- four CVBS, one S -VHS input, one CVBS output
- two RGB/YC r C b component inputs, one Fast Blank (FB) input
- integrated high -quality A/D converters and associated clamp and AGC circuits
- multi-standard sync processing
- linear horizontal scaling (0.25 ... 4), as well as non -linear horizontal scaling ?Panorama -vision?
- PAL+ preprocessing
- line-locked clock, data and sync, or 656 -output interface
- peaking, contrast, brightness, color saturation and tint for RGB/ YC r C b and CVBS/ S -VHS
- high-quality soft mixer controlled by Fast Blank
- PIP processing for four pict ure sizes (1/4, 1/9, 1/16 or 1/36 of normal size) with 8 -bit resolution
- 15 predefined PIP display configurations and expert mode (fully programmable)
- control interface for external field memory
2
- IC-bus interface
- one 20.25-MHz crystal, few external components
- 80-pin PQFP package
