Integrated Device Technology Synchronization System For IEEE 1588 82P33931-1BAG8

The 82P33931-1 Synchronization System for IEEE 1588 is comprised of software and hardware designed to meet the needs of IEEE 1588 slave clock and master clock applications. The system includes Precision Time Protocol ( PTP ) stack software (Stack) and clock recovery servo software (Servo) that runs on an external processor; and Synchronization Management Unit ( SMU ) hardware. The included PTP stack is IEEE 1588-2008 compliant and is used to control the exchange of messages between IEEE 1588 masters and slaves.The Servo recovers accurate and stable electrical synchronization signals from packet based references generated by IEEE 1588 masters. The Servo is capable of filtering the effects of Packet Delay Variation ( PDV ) often present in IEEE 1588 unaware networks. The SMU hardware 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).
