Title:
CLOCK DISTRIBUTION METHOD AND APPARATUS IN NETWORK
Document Type and Number:
WIPO Patent Application WO/2020/154840
Kind Code:
A1
Abstract:
The present disclosure relates to a clock distribution method and apparatus in a network. A method performed at a clock distribution apparatus comprises: receiving a first clock signal from a first clock source; receiving a second clock signal from a second clock source; calculating an offset difference between the first clock signal and the second clock signal; compensating the second clock signal with the offset difference; determining to switch from the first clock source to the second clock source; and outputting the compensated second clock signal. The offset difference between the first clock signal and the second clock signal is calculated and used to compensate the second clock signal. Then, the compensated second clock signal is transferred to the downstream. The switching of the clock signal will be smoother for the downstream.
