摘　　要：介绍了AMBE-2000的工作原理及其应用,并结合实例给出了数字语音传输系统中AMBE-2000与TLV320AIC10的A/D、D/A接口电路。AMBE-2000是DVSI(Digital Voice System·Inc)公司的语音压缩解压缩芯片,它采用AMBE语音压缩技术,具有语音音质好和编码波特率低、功耗低等优点;TLV320AIC10是TI公司的低功耗∑-Δ型16位A/D、D/A音频接口芯片。应用AMBE-2000的数字语音传输系统可以在低速率下提供优良的语音质量,并能实现全双工、实时语音压缩解压缩功能,因此在卫星通信、移动通信等领域有着广泛的应用。In this paper, the principle and applications of the AMBE - 2000 is introduced. Also, with an example, the A/D and D/A interface circuit between AMBE - 2000 and TLV320AIC10 in digital voice transmission system are introduced. AMBE - 2000 is a voice codec product of DVSI （ Digital Voice System. Inc. ）. Using the AMBE voice compression technology, AMBE - 2000 provides high voice quality at low data rate with lower power consumption. TLV320AIC10 is a 16-bit A/D and D/A converter using over sampling sigma-delta technology. Digital voice transmission system using AMBE - 2000 is widely used in the filed of satellite communications and mobile communications.
