AD725集成电路（IC）的编码器解码器转换器规格书PDF中文资料

AD725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AD725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。

PRODUCT DESCRIPTION

The AD725 is a very low cost general purpose RGB to NTSC/PAL encoder that converts red, green and blue color component signals into their corresponding luminance (baseband amplitude) and chrominance (subcarrier amplitude and phase) signals in accordance with either NTSC or PAL standards. These two outputs are also combined on-chip to provide a composite video output. All three outputs are available separately at voltages of twice the standard signal levels as required for driving 75 Ω, reverse-terminated cables.
