ADV7177KS集成电路（IC）的编码器解码器转换器规格书PDF中文资料

ADV7177KS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ADV7177KS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 ADV7177/ADV7178 is an integrated digital video encoder that converts Digital CCIR-601 4:2:2 8- or 16-bit component video data into a standard analog baseband television signal compatible with worldwide standards. The 4:2:2 YUV video data is interpolated to two times the pixel rate. The color difference components (UV) are quadrature modulated using a subcarrier frequency generated by an on-chip 32-bit digital synthesizer (also running at two times the pixel rate).
