ADV7343WBSTZ-RL

视频 IC Multiformat Video Encoder

Product Details

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, SVideo 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. The parts also support embedded EAV/SAV timing codes, external video synchronization signals, and the I2C communication protocol.

In addition, simultaneous SD and ED/HD input and output are supported. 216 MHz SD and ED and 297 MHz HD oversampling ensures that external output filtering is not required, while full-drive DACs ensure that external output buffering is not required.

Cable detection and DAC auto power-down features keep power consumption to a minimum.
