摘要
AC4830xC-C是美国AudioCodes公司生产的语音专用芯片 ,它支持多种码率的语音编解码国际标准 ,同时可提供传真和数据中继功能。而TCM38C17则是美国TI公司的语音PCM编码芯片。文章介绍了两种芯片的基本性能及工作原理 ,并给出了一种基于这两种芯片设计的四路语音编解码系统的实现方案。
AC4830xC-C is a voice processor produced by AudioCodes Inc. It is capable of several CODECS of different rates advised by ITUT. TCM38C17 is a PCM encoder chip produced by Ti Inc. The basic property and mechanism of these chips were introduced in this article. Furthermore, a scheme of the four-channel voice CODEC based on the two chips is proposed.
