5 / 78 page  ADVANCE INFORMATION VPC 323xD, VPC 324xD Micronas 5 Comb Filter Video Processor 1. 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 sepa- rator 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 inter- face (VPC 323xD) – display and deflection control (VPC 324xD) – peaking, contrast, brightness, color saturation and tint for RGB/ YCrCb and 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 1.1.
