SDH微波传输中的同步时钟

Synchronous Clock in SDH Microwave Transmission

介绍了广电SDH数字微波电路中时钟同步系统的设计方法。结合广州广电SDH数字微波电路的时钟同步系统方案提出了在实际设计中应该注意的问题,列举了同步时钟系统中常见的时钟配置电路;同时简要介绍了SDH微波传输电路同步时钟的类型、结构、原理等。

This article describes the design method of the clock synchronization system in SDH digital microwave circuit. Combining with the practice in Guangzhou, the paper presents the problems that should be paid attention to in the actual design and enumerates the common circuit in synchronous clock system. Meantime, it introduces the type, structure and principle of the SDH microwave transmission circuit synchronous clock.
