The ADV7343BSTZ is a high speed, Digital-to-Analog Video Encoder. Six high speed, 11-bit video DACs provide support for composite (CVBS), S-Video (Y-C) and component (YPrPb/RGB) analog outputs in standard definition (SD), enhanced definition (ED) or high definition (HD) video formats. The device has a 24-bit pixel input port that can be configured in a variety of ways. SD video formats are supported over an 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 colour spaces. The parts also support embedded EAV/SAV timing codes, external video synchronization signals and I²C® communication protocol. In addition, simultaneous SD and ED/HD input and output are supported. Full-drive DACs ensure that external output buffering is not required, while 216MHz (SD and ED) and 297MHz (HD) oversampling ensures that external output filtering is not required.
