SAA7126H Description
SAA7127H encodes digital Cb-Y-Cr video data to an NTSC or PAL CVBS or S-video signal. Simultaneously, RGB or bypassed but interpolated Cb-Y-Cr signals are available via three additional Digital-to-Analog Converters (DACs). The circuit at a 54 MHz multiplexed digital D1 input port accepts two CCIR patible Cb-Y-Cr data streams with 720 active pixels per line in 4.
