摘要
A precise-clock synchronization method and system and a precise-clock frequency/time synchronization device are provided. In the embodiments of the present invention, two time stamp engines are provided at a slave clock side. A relative time stamp engine provides a relative arrival time stamp. An absolute time stamp engine provides an absolute arrival time stamp. The frequency/time synchronization is calculated by using different time stamps obtained from different time stamp engines, so the frequency synchronization and time synchronization of the master clock and the slave clock may be separately accomplished, and one synchronization function may be enabled or disabled. Therefore, the frequency synchronization and time synchronization of the master clock and the slave clock do not interfere with each other, thus greatly reducing the occupied link bandwidth resources.
