FPGA-based high-precision network time synchronization research and Implementation

摘要：

This study is based on the 1588 network clock synchronization technology. Clock synchronization of distributed systems is a very important element in the communications, automation, and testing equipment especially for the current LXI Bus. Now there are some synchronization protocols like NTP. But it just has millisecond synchronization accuracy. In many areas such as instrument system, that accuracy is not enough. Therefore, higher synchronization accuracy is required. This paper presents a model for high accuracy of the clock, detailed analysis of the factors that affect clock synchronization and proposed to solve the key technology and solution. These technologies not only changed the clock operation mode, but also access to technology to improve the timestamp. The results show that the synchronization accuracy can be achieved nanosecond.
