Patent ID: 11924319
Assignee: NEC PLATFORMS, LTD.
Field: Telecommunications (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 2:
3. The synchronization device according to claim 2, wherein
the frequency synchronizer includes a digital PLL processor and a recovered clock counter,
the digital PLL processor performs a phase comparison between the synchronous Ethernet signal and the recovered clock from the recovered clock counter,
the first digital controlled oscillator generates the frequency control information based on a result of the phase comparison,
the recovered clock counter generates the recovered clock based on the frequency control information,
the time synchronizer includes a PTP (Precision Time Protocol) servo processor,
the PTP servo processor performs a time comparison between a time based on the time packet and the time synchronization signal from the time synchronization signal generator, and
the second digital controlled oscillator generates the time control information based on a result of the time comparison.
