Si5348 Network Synchronizer

3. Functional Description The Si5348 offers three DSPLLs that have identical performance and flexibility which can be independently configured and controlled through the serial interface. Each of the DSPLLs support locked, free-run, and holdover modes of operation with an optional DCO mode for IEEE .

Si5348 Rev D Data Sheet Network Synchronizer for SyncE/ 1588 PTP Telecom Boundary (T-BC) and Slave (T-SC) Clocks The Si5348 combines the industry’s smallest footprint and lowest power network synchronizer clock with unmatched frequency synthesis flexibility and ultra-low jitter. The Si5348 is ideally suited for wireless backhaul, IP radio, small and macro cell wireless communications systems, and data center switches requiring both traditional and packet based network synchronization. The three.
