STA016T集成电路（IC）的编码器解码器转换器规格书PDF中文资料

STA016T属于集成电路（IC）的编码器解码器转换器。由意法半导体集团制造生产的STA016T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。

DESCRIPTION

The STA016 is a single chip MPEG 1, 2 and 2.5 Layer III audio decoder with embedded CDROM decoding capability. It can be easily connected to most existing CDDSP devices via a software configurable serial link. A tipical application block diagram is show in Figure 1. Besides MPEG decoding the device can also perform ADPCM encoding/decoding from different audio sources and the encoded stream, for instance, can be stored on an external flash memory.

A useful bypass mode allow using this device also as an audio processor for volume and tone controls.
