Integrated Device Technology Synchronization Management Unit (SMU) for IEEE 1588 and 10G/40G Synchronous Ethernet 82P33831ABAG8

The 82P33831 Synchronization Management Unit ( SMU ) provides tools to manage timing references, clock sources and timing paths for IEEE 1588 and Synchronous Ethernet (SyncE) based clocks. The device supports up to three independent timing paths that control: IEEE 1588 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-to-output phase skew can all be precisely managed. The device outputs low-jitter clocks that can directly synchronize 40GBASE -R, 10GBASE -R and 10GBASE -W and lower-rate Ethernet interfaces; as well as CPRI / OBSAI , SONET / SDH and PDH interfaces and IEEE 1588 Time Stamp Units (TSUs).
