VPC 323xD 1. Introduction Comb Filter Video Processor 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 nonlinear horizontal scaling 'Panoramavision'. - PAL+ preprocessing. - Line-locked clock, data and sync, or 656-output interface. - 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 (1/4, 1/9, 1/16, or 1/36 of normal size) with 8-bit resolution. - Control interface for external field memory. - I2C-bus interface. - One 20.25-MHz crystal, few external components. - 80-pin PQFP package.

VPC 323xD
Comb Filter Video Processor
1. 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 nonlinear horizontal scaling Panoramavision .
- PAL+ preprocessing.
- Line-locked clock, data and sync, or 656-output interface.
- 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 (1/4, 1/9, 1/16, or 1/36 of normal size) with 8-bit
resolution.
- Control interface for external field memory.
- I
2
C-bus interface.
- One 20.25-MHz crystal, few external components.
- 80-pin PQFP package.
