CH7203 - ETC

CH7203 MPEG to TV Encoder

The CH7203 video encoder integrates a dual PLL clock generator and a digital NTSC/PAL video encoder. By generating all essential clock signals for MPEG playback, and converting digital video inputs to either NTSC or PAL video signals, the CH7203 is an essential component of any low-cost solution for video-CD playback machines. The CH7203 dual PLL clock synth.
