A Design for Timing Pulse Low Jitter Deliverring

In this paper,a timing pulse low-jitter transmission scheme is proposed for time synchronization system.First,the design on timing pulse low-jitter transmission is introduced.Then, the key technologies such as digital interpolation, phase-locked loop, modem and phase-ambiguity detection are discussed. Finally, the implementation approach of timing pulse low-jitter transmission system is proposed and the performance test results are analyzed.The pulse transmission jitter is observed by using oscilloscopes and controlled within 4ns, and its validity is proved in practical engineering.
