VPX 322xE
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
