Abstract
In order to realize the unified exchange of different types and sizes of business,the reference clocks used in the unified exchange technology are required to align and lock the phase of reference clocks.This article uses frame signal from the E1 in-terface to transmit the phase information of reference clocks.The information interaction of the frames among multiple devices and Field Programmable Gate Array (FPGA)are used to process the information,which can adj ust the phase of clocks in the equipments.Simulation results show that the phase of reference clocks can be locked.This scheme is processed by hardware channel,which will not generate loss or misrepresentation of phase information,and can effectively solve the clock phase loc-king problem among devices.关键词
