Title:
METHOD FOR REALIZING HIGH-FREQUENCY CARRIER SYNCHRONIZATION, AND RELATED APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/046999
Kind Code:
A1
Abstract:
A method for realizing high-frequency carrier synchronization, and a related apparatus. The method for realizing high-frequency carrier synchronization comprises: a CPLD operation chip of a slave device acquiring, from a bus, a host high-frequency synchronization square signal sent by a host device; the CPLD operation chip of the slave device acquiring a slave high-frequency synchronization square signal sent by an MCU main control chip of the slave device; the CPLD operation chip of the slave device determining phase adjustment information about a carrier of the slave device according to the host high-frequency synchronization square signal and the slave high-frequency synchronization square signal; the CPLD operation chip of the slave device transmitting a direction adjustment signal carrying the phase adjustment information to the MCU main control chip of the slave device; and the MCU main control chip of the slave device adjusting the carrier of the slave device according to the direction adjustment signal. The technical solution of the present invention can realize master-slave synchronization where an MCU main control chip does not have a capture port.
