ADV7344BSTZ

多格式视频编码器六，14位噪声整形视频DAC Multiformat Video Encoder Six 14-Bit Noise Shaped Video DACs

Product Details

The ADV7344 is a high speed, digital-to-analog video encoder in a 64-pin LQFP package. Six high speed, NSV, 3.3 V, 14-bit video DACs provide support for composite CVBS, S-Video YC, and component YPrPb/RGB analog outputs in either standard definition SD, enhanced definition ED or high definition HD video formats.

The ADV7344 has a 30-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 ADV7344 also supports embedded EAV/SAV timing codes, external video synchronization signals, and the I2C communication protocol.

In addition, simultaneous SD and ED/HD input and output is 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.
