【文字介绍】

ADV7390/ADV7391/ADV7392/ADV7393均属于单芯片、高速、数模视频编码器系列。三个2.7 V/3.3 V 10位视频DAC支持标清(SD)或高清(HD)视频格式的复合(CVBS)、S视频(YC)或分量(YPrPb/RGB)模拟输出。

这些编码器针对低功耗操作进行了优化,尺寸极小,并且只需很少的外部器件,非常适合要求电视输出功能的便携式和功耗敏感型应用。有线电视信号检测和DAC自动关断特性可确保功耗保持最低。

ADV7390/ADV7391配有一个8位视频输入端口,通过SDR接口支持标清视频格式,通过DDR接口支持高清视频格式。
ADV7392/ADV7393配有一个16位视频输入端口,可采用多种方式进行配置。同时支持标清RGB输入。该系列所有器件均支持嵌入式EAV/SAV时序码、外部视频同步信号以及I2C通信协议。
