VPX 3225D, VPX 3224D
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 with Y/C comb filter
– two 8-bit video A/D converters with clamping and auto-
– four analog inputs with integrated selector for:
– 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
– horizontal resizing between 32 and 864 pixels/line
– vertical resizing by line dropping
– high-quality anti-aliasing filter
– scaling controlled peaking and coring
matic gain control (AGC)
