同步数据接口时钟关系分析

Analysis of timing signal relationship between synchronous interchange circuits

介绍了同步传输常用的技术标准和符合国际规范的同步数据与定时信号关系,根据我国航天测控网中常用通信设备的时钟方式设置,对某国军标中存在的问题进行了探讨,并提出了修改意见。通过对高速数据在不同时钟方式下的传输效果比较,指出了合理选择时钟的重要性,可为实际的工程应用提供参考。

The technical standard usually used in synchronous data transmission and the relationship between synchronous data and timing circuits conforming to the international criterion are introduced. According to the liming mode settings of communication equipments in China spacecraft tracking and control field, the question in one of Chinese military criterions is discussed and a better suggestion is put forward. Through comparison of high speed data transmission effect in different mode, the importance of timing selection comes out. It can provide reference for engineering applications.
