NXP Semiconductors SAA7124
The SAA7124; SAA7125 encodes digital YUV video data to an NTSC or PAL CVBS plus RGB or alternatively to S-Video and CVBS output. The circuit accepts CCIR compatible YUV data with 720 active pixels per line in 4 : 2 : 2 multiplexed formats, for example MPEG decoded data. It includes a sync/clock generator and on-chip Digital-to-Analog Converters (DACs).| Part No. | SAA7124 |
