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 features 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

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

and CVBS/ S-VHS
– high-quality soft mixer controlled by Fast Blank
– PIP processing for four picture 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
– I
