PRELIMINARY DATA SHEET

Video Pixel Decoder

Release Note: This data sheet describes functions

and characteristics of VPX 322xD–C3 and D4. Revi-

sion bars indicate significant changes to the pre-

vious edition.

1. Introduction

The Video Pixel Decoders VPX 3225D and VPX 3224D

are the second generation of full feature video acquisi-

tion ICs for consumer video and multimedia applica-

tions. All of the processing necessary to convert an ana-

log video signal into a digital component stream have

been integrated onto a single 44-pin IC. Moreover, the

VPX 3225D provides text slicing for intercast, teletext,

and closed caption. Both chips are pin compatible to

VPX 3220A, VPX 3216B, and VPX 3214C. Notable fea-

tures include:

Video Decoding

– multistandard color decoding:

• NTSC-M, NTSC-443

• PAL-BGHI, PAL-M, PAL-N, PAL-60

• SECAM

• S-VHS

– NTSC with Y/C comb filter

– 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

(version D4 only)

Video Processing

– hue, brightness, contrast, and saturation control

– dual window cropping and scaling

– horizontal resizing between 32 and 864 pixels/line

– vertical resizing by line dropping

– high-quality anti-aliasing filter

– scaling controlled peaking and coring

Video Interfacing

– YCbCr 4:2:2 format

– ITU-R 601 compliant output format

– ITU-R 656 compliant output format

– BStream compliant output format

– square pixel format (640 or 768 pixel/line)

– 8-bit or 16-bit synchronous output mode

– 13.5 MHz/16-bit and 27 MHz/8-bit output rate

– VBI bypass and raw ADC data output

Data Broadcast Support (VPX 3225D only)

– high-performance data slicing in hardware

– multistandard data slicer

• teletext, intercast, wavetop,

• WebTV for windows, EPG services

– programmable to new standards via I2C

– automatic slice level adaptation

– VBI and Full-Field mode

– data insertion into video stream

– simultaneous acquisition of teletext, VPS, WSS, and

caption

Miscellaneous

– 44-pin PLCC package

– total power consumption of below 1 W

– I2C serial control, 2 different device addresses

– single on-chip clock generation, only one crystal need-

ed for all standards

– user programmable output pins

– power-down mode

– IEEE 1149.1 (JTAG) boundary scan interface

Software Support
