  • Clock synchronization system, method, and apparatus for communication
    Patent number: 8295267
    Abstract: When the synchronization information, transmitted from a synchronization information output unit of a clock master side device, is detected by a synchronization information detection unit, the clock slave side device associates the synchronization information with the timestamp information at the time of detection of the synchronization information. Based on the timestamp information associated with the currently received synchronization information, the timestamp information associated with at least one synchronization information up to the synchronization information received last time and transmission period information of the synchronization information, a calculation/decision unit decides whether or not a predetermined condition is met. When the condition is met, the calculation/decision unit supplies the currently received synchronization information to a clock synchronization technique function unit.
