1.1. System Architecture
The block diagram (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 video processing stage resizes the

samples, adjusts the contrast and brightness,
and interpolates the chroma. The text slicer extracts
lines with text information and delivers decoded data
bytes to the video interface.
Note:
The VPX 322xE is register compatible with the
VPX 322xD family, but not with VPX 3220A, VPX 3216B,
and VPX 3214C family.
