TV ENCODER

GENERAL DESCRIPTION

FUNCTIONAL BLOCK

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.

Figure-1 W9952QP Functional Block

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.

APPLICATIONS

W9952QP is designed for digital video applications,

such as VCDs (Video CDs), STBs (Set-Top Box) and

video games.

The W9952QP can operate at power-down mode by

selecting the SLEEP pin.

Figure 2 shows a typical configuration of W9952QP

application.

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.
