Synchronization device and synchronization method

A synchronization device adapted to synchronize a first node and a second node, wherein the first node supports a first time protocol profile, and the second node supports a second time protocol profile, wherein the synchronization device comprises:

• a counter providing a system operating time;
• a phase-locked loop circuit providing a clock signal;
• a first time protocol stack circuit coupled to the first node, wherein the first time protocol stack circuit communicates with the first node based on the first time protocol profile to obtain first synchronization information and second synchronization information;
• a servo circuit coupled to the phase-locked loop circuit, the counter and the first time protocol stack circuit, wherein the servo circuit calculates a time delay according to the first synchronization information and corrects the system operating time according to the time delay to generate a corrected system operating time, wherein the servo circuit calculates a frequency drift according to the first synchronization information and the second synchronization information and corrects the clock signal according to the frequency drift to generate a corrected clock signal;
• a second time protocol stack circuit coupled to the servo circuit and the second node, wherein the second time protocol stack circuit communicates with the second node based on the second time protocol profile, so as to provide the second node with third synchronization information according to the corrected system operating time and the corrected clock signal.
