Introduction
The Video Pixel Decoders VPX 3225D and VPX 3224D are the second generation 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 3225D provides text slicing for intercast, teletext, and closed caption. Both chips are pin compatible to VPX 3220A, VPX 3216B, and VPX 3214C. Notable features 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 automatic 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
