Video Pixel Decoder Family
Release Notes: Revision bars indicate significant
changes to the previous edition.
1. Introduction
The Video Pixel Decoder (VPX) is a full-feature video ac-
quisition IC for consumer video and multimedia applica-
tions. All of the processing necessary to convert an ana-
log video signal into a digital component stream has
been integrated onto a single 44-pin IC. Its notable fea-
tures include:
– single chip multistandard color decoding NTSC/PAL/
SECAM/S-VHS, NTSC with chroma comb filter.
– two 8-bit video A/D converters with clamping and au-
tomatic gain control (AGC)
– four analog inputs with integrated selector for
3 composite video sources (CVBS), or
2 YC sources (SVHS), or
2 composite video sources and one YC source.
– automatic standard detection
– horizontal and vertical sync detection for all standards
– hue, brightness, contrast, and saturation control
– horizontal resizing between 32 and 1056 pixel/line
– vertical resizing by line dropping
– high quality anti-aliasing filter (VPX 3220 A only)
– ITU-R601 level compatible
– YCbCr (4:4:4, 4:2:2, or 4:1:1) or
γ-corrected RGB 4:4:4 (15, 16, or 24 bits)
compressed Video (DPCM 8 bit)
(VPX 3214 C supports only YCrCb 4:2:2)
– alpha key generation
(only VPX 3220 A, and VPX 3216 B)
– 8-bit or 16-bit synchronous output mode
– asynchronous output mode via FIFO with status flags
– VBI bypass mode for Teletext, Closed Caption, and
Intercast
– 44-pin plastic package (PLCC, TQFP)
– total power consumption under 1 W
– I2C serial control, selectable power-up default state
– on-chip clock generation
– IEEE 1149.1 (JTAG) boundary scan interface
VPX 3220 A, VPX 3216 B, and VPX 3214 C are pin and
software compatible, but differ slightly in the feature set.
1.1. Difference between VPX 3220 A and VPX 3216 B
VPX 3220 A performs low-pass filtering before resam-
pling the data, whereas VPX 3216 B does not. For more
info, see Fig. 1–1 and refer to section 2.3.
1.2. Difference between VPX 3216 B and VPX 3214 C
The VPX 3214 C is based on the VPX 3216 B but without
color space conversion. VPX 3214 C supports only
YCbCr 4:2:2.
1.3. System Architecture
The block diagram in Fig. 1–1 illustrates the signal flow
through the VPX. A sampling stage performs 8-bit A/D
conversion, clamping, and AGC. The color decoder sep-
arates the luma and chroma signals, demodulates the
chroma, and filters the luminance. A sync slicer detects
the sync edge and computes the skew relative to the
sample clock. The component processing stage resizes
the YCbCr samples, adjusts the contrast and bright-
ness, and interpolates the chroma. The color space
stage contains a dematrix, a γ–1 correction, a DPCM-like
encoder, and an alpha key generator. The format stage
arranges the samples into the selected byte format and
(in the case of asynchronous output) buffers the data for
output.
