AI Technical Summary
Existing technologies suffer from a lack of synchronization between the local clock and the IRIG-B source clock when generating second pulse signals, resulting in large synchronization errors and failing to meet the high-precision time synchronization requirements of scenarios such as power systems.
The reference time code generation unit analyzes the precise timing edge of the time code standard signal and combines it with the phase-locked loop's phase-locking mechanism to generate a target clock signal and a second pulse signal synchronized with the IRIG-B source clock. Precise phase alignment is achieved through phase detection adjustment of the phase-locked loop.
It achieves synchronization between the target clock signal and the time code standard signal, reduces the jitter of the PPS signal, and improves the accuracy of time synchronization.
