ADVANCE INFORMATION
VPC 323xD, VPC 324xD
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
