Integrated Device Technology Synchronization Management Unit (SMU) for IEEE 1588 and Synchronous Ethernet 82P33813NLG8

The 82P33813 Synchronization Management Unit ( SMU ) provides tools to manage timing references, clock sources and timing paths for IEEE 1588 / Precision Time Protocol ( PTP ) and Synchronous Ethernet (SyncE) based clocks. The device supports up to three independent timing paths that control: PTP clock synthesis; SyncE clock generation; and general purpose frequency translation. The device supports physical layer timing with Digital PLLs (DPLLs) and it supports packet based timing with Digitally Controlled Oscillators (DCOs). Input-to- input, input-to-output and output-tooutput phase skew can all be precisely managed. The device outputs low-jitter clocks that can directly synchronize lower-rate Ethernet interfaces; as well as CPRI / OBSAI , SONET / SDH and PDH interfaces and IEEE 1588 Time Stamp Units (TSUs).
