| Abstract: | We presented a clock synchronization method that contained a clock adjusting algorithm and a frequency compensated clock to achieve precise synchronization among distributed clocks based on IEEE 1588 protocol. Further, we presented its application on Ethernet and implementation of the frequency compensated clock in a field programmable gate array (FPGA) as experiments. The results indicate that this method can support sub-microsecond synchronization with inexpensive standard crystal oscillators. |
