Fenglei Wang, Wenhai Li, Yiping Wang, Zhao Xiuli · 2007
The precise clock synchronization technique based on IEEE1588 protocol is one of the key techniques of LXI. This technique is used in LXI class B device. First, the development trend of LXI is introduced in this paper. Then the basic principle of precise clock synchronization technique is analyzed, precise clock synchronization based on MCU platform is designed and the LXI class B module is designed. In order to improve the precision of clock synchronization, FPGA is used in the system to stamp time label for Ethernet data.
