Abstract
A Synchronous Ethernet (SyncE) network device includes a pair of phase-locked loops including a first phase-locked loop responsive to a SyncE input clock and a second phase-locked loop coupled to the first phase-locked loop. The second phase-locked loop is configured to be simultaneously lockable to both the SyncE input clock via the first phase-locked loop and an IEEE 1588 packet stream, during a locked mode of operation, and also lockable to the SyncE input clock during a holdover mode of operation which is triggered in response to a failure of the IEEE 1588 packet stream.
