多格式视频编码器六， 11位， 297 MHz的DAC的 Multiformat Video Encoder Six, 11-Bit, 297 MHz DACs
GENERAL DESCRIPTION
The ADV7342/ADV7343 are high speed, digital-to-analog video encoders in a 64-lead LQFP package. Six high speed, 3.3 V, 11-bit video DACs provide support for composite CVBS, S Video Y/C, and component YPrPb/RGB analog outputs in either standard definition SD, enhanced definition ED, or high definition HD video formats.
The ADV7342/ADV7343 each have a 24-bit pixel input port that can be configured in a variety of ways. SD video formats are supported over a SDR interface and ED/HD video formats are supported over SDR and DDR interfaces. Pixel data can be supplied in either the YCrCb or RGB color spaces.
