数据通信和语音通信越来越紧密的结台,业已成为现今网络和通信技术的主流。不论是Routing Switch,还是Voice Mail Sever Gateway,抑或Calling Center等,无一不涉及到语音编码技术。美国新涛半导体公司推出的NW1068正是为满足这些需求应运而生的。目前,业内普遍采用的语言编译码器多为单通道、二通道,偶尔也用到四通道的PCM编译码器。一方面,由于这些芯片集成度偏低,增加了系统设计排板的难度,并且,过多的走线可能会增大系统的噪声,影响系统的性能;另一方面,这些芯片的功能往往不够全面,在应用系统设计中不能
Closer and closer integration of data and voice communications has become the mainstream of today’s networking and communications technologies. Whether Routing Switch, or Voice Mail Server Gateway, or Calling Center, all involve speech coding technology. The NW1068, introduced by Xintao Semiconductor Corporation, was created to meet these needs. Currently, the industry commonly used language codecs are mostly single-channel, two-channel, and occasionally also used four-channel PCM codec. On the one hand, due to the low level of integration of these chips, the difficulty of designing the layout of the system is increased, and excessive routing may increase the system noise and affect the system performance; on the other hand, the functions of these chips are often insufficient Comprehensive, can not be applied in system design
