VPC32300C5

Introduction

The VPC 323xD/324xD is a high-quality, single-chip video front-end, which is targeted for 4:3 and 16:9, 50/60 and 100/120 Hz TV sets. It can be combined with other members of the DIGIT3000 IC family (such as DDP 33x0A/B, TPU 3040) and/or it can be used with 3rd-party products.

The main features of the VPC 323xD/324xD 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 associ ated 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 (VPC 323xD)
– line-locked clock, data and sync, or 656-output interface (VPC 323xD)
– display and deflection control (VPC 324xD)
– peaking, contrast, brightness, color saturation and tint for RGB/ YC rCband 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
