ADV7181C集成电路（IC）的编码器解码器转换器规格书PDF中文资料

ADV7181C属于集成电路（IC）的编码器解码器转换器。由亚德诺半导体技术有限公司制造生产的ADV7181C编码器，解码器，转换器该系列产品可用于将信息封装或编码为适合于传输或存储的格式，和/或在通信路径的另一端执行逆运算，通常是通过使用某些形式的调制过程。示例包括从数字数据生成模拟视频信号的器件（反之亦然）；基于传输目的对按钮的状态进行编码的器件（实现远程控制功能）；以及便于将标准 UART 连接到标准红外收发器的器件。

GENERAL DESCRIPTION

The ADV7181C is a high quality, single-chip, multiformat video decoder and graphics digitizer. This multiformat decoder supports the conversion of PAL, NTSC, and SECAM standards in the form of composite or S-Video into a digital ITU-R BT.656 format. The ADV7181C also supports the decoding of a component RGB/YPrPb video signal into a digital YCrCb or RGB DDR pixel output stream. The support for component video includes standards such as 525i, 625i, 525p, 625p, 720p, 1080i, and many other HD and SMPTE standards. Graphics digitization is also supported by the ADV7181C; it is capable of digitizing RGB graphics signals from VGA to SXGA rates and converting

them into a digital DDR RGB or YCrCb pixel output stream. SCART and overlay functionality are enabled by the ability of the ADV7181C to process simultaneously CVBS and standard definition RGB signals. The mixing of these signals is controlled by the fast blank pin.
