Preliminary
W9952Q
GENERAL DESCRIPTION
The W9952Q digital video encoder converts YCrCb (4:2:2) 8-bit data into
analog composite video and Y/C video signals. The video format is 525-line (M)
NTSC/PAL or 625-line (B,D,G,H,I,M,Nc) PAL.
The W9952Q can operate at master or slave mode. The data rate can be
CCIR601 or square pixel. At slave mode, the W9952Q can auto detect 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 input YCrCb data are converted into YUV signals. The chroma data are
then low passed by a 1.3 MHz filter and modulated by a color subcarrier.
The W9952Q has two DAC outputs which can output two composite video or
Y/C S-video signal.
The W9952Q can operate at power-down mode by selecting the SLEEP pin.
The W9952Q is designed for digital video applications such as VCD, DVD, and
video games.
