Timing information recovering method for clock synchronization between master and slave nodes involves adjusting frequency of slave clock to match master clock using offset of time grid

摘要

A series of timing packets is exchanged between the master node and slave nodes. An offset of time grid relative to the master and slave clocks is measured. The frequency of slave clock is adjusted to match the master clock using the measured offset of time grid. The difference between the time grids and the frequency offset is used to control a frequency synthesizer generating slave clock. An independent claim is also included for arrangement for recovery timing information.
