12.31. VPC3230D

12.31.1. 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 colour decoder PAL/NTSC/SECAM including all substandards
• four CVBS, one S-VHS input, one CVBS output
• two RGB/YC C component inputs, one Fast Blank (FB) input
r b
• 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
• 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
2
• I C-bus interface
• one 20.25-MHz crystal, few external components
• 80-pin PQFP package
