GENERAL DESCRIPTION
The W9952QP digital video encoder converts
YCbCr (4:2:2) 8-bit data into analog composite
video and Y/C video signals. It accepts ITU-601/656
or square pixel input formats, and the output video is
formatted to be compatible with 525-line (M) NTSC/
PAL or 625-line (B,D,G,H,I,M,Nc) PAL TV System.
The W9952QP operates in both master or slave
modes. At slave mode, the W9952QP auto detects
the input video format from the HSYNCN and
VSYNCN pins and generates the corresponding
video signals. At master mode, It generates the
required video timing internally according to the
configuration.
The W9952QP has two DAC outputs which can
output either two composite video signals or one Y/C
S-video signal. The W9952QP doesn't output
composite video and S-video simultaneously.
The W9952QP can operate at power-down mode by
selecting the SLEEP pin.
The W9952QP is designed to connect to MPEG1
and MPEG2 video decoders without glue logic. All
video processing is done digitally and requires no
external adjustment and no software programming is
required.
