Abstract: A distributed synchronization system including a management device and a plurality of synchronization devices is provided. The management device includes a network input interface and a network output interface, and is configured to: decode a precision time protocol packet to obtain a reference 1 pulse per second signal, a reference frequency signal, and reference time of day information; send a reference synchronization signal and a reference control signal to a first synchronization device through the network output interface. The reference synchronization signal includes the reference 1 pulse per second signal, the reference frequency signal and the reference time of day information. The reference control signal requests the first synchronization device to synchronize with the management device.
