Introduction

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/YCrCb 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 ‘Panoramavision’

– PAL+ preprocessing

– line-locked clock, data and sync, or 656-output interface

– peaking, contrast, brightness, color saturation and tint for RGB/ YC rC band CVBS/S-VHS

– high-quality soft mixer controlled by Fast Blank

– PIP processing for four picture sizes ( , or of normal size) with 8-bit resolution

– 15 predefined PIP display configurations and expert mode (fully programmable)

– control interface for external field memory

– I2C-bus interface

– one 20.25-MHz crystal, few external components

– 80-pin PQFP package
