ADVANCE INFORMATION

Video Pixel Decoders

Note: This data sheet describes functions and char-

acteristics of VPX 322xE-A1.

1. Introduction

The Video Pixel Decoders VPX 322xE are the third gen-

eration of full feature video acquisition ICs for consumer

video and multimedia applications. All of the processing

necessary to convert an analog video signal into a digital

component stream have been integrated onto a single

44-pin IC. Moreover, the VPX 3225E and VPX 3226E

provide text slicing for intercast, teletext, and closed

caption. For improved Y/C separation, the VPX 3226E

includes an adaptive 4H comb filter. All chips are pin

compatible to VPX 3220A, VPX 3214C, and VPX 322xD.

Their notable features include:

Video Decoding

– high-performance adaptive 4H comb filter Y/C separa-

tor with adjustable vertical peaking (VPX 3226E only)

– multistandard color decoding:

• NTSC-M, NTSC-443

• PAL-BDGHI, PAL-M, PAL-N, PAL-60

• SECAM

• S-VHS

– two 8-bit video A/D converters with clamping and auto-

matic gain control (AGC)

– four analog inputs with integrated selector for:

• 3 composite video sources (CVBS), or

• 2 Y/C sources (S-VHS), or

• 2 composite video sources and one Y/C source.

– horizontal and vertical sync detection for all standards

– decodes and detects Macrovision 7.1 protected video

Video Processing

– hue, brightness, contrast, and saturation control

– dual window cropping and scaling
