1 ?2017 integrated device technology, inc. april 5, 2017 82p33914-1 datasheet description ieee 1588-2008 precision time protocol (ptp) is a packet-based syn- chronization mechanism used in packe t-switched networks. ptp synchro- nizes the clocks of different devices with the most accurate clock on the network ? usually a precise, grandmas ter clock, such as one using a pri- mary reference time cl ock (prtc) time signal. the 82p33914-1 is a soft- ware and hardware system that can operate as a ptp slave or ptp master. as a ptp slave the 82p33914- 1 recovers accurate and stable electrical synchronization signals fr om a packet based reference gener- ated by a ptp master. as a ptp master the 82p33914-1 can lock to a sta- ble electrical clock source and generate packet based ptp references for downstream ptp slaves the 82p33914-1 is available with seve ral software and hardware options. the software options are outlined in table 1 by root part number. the hardware options depend on the choice of synchronization management unit (smu) hardware; the smu hardware documentation is listed in table 3 by root part number. system component documentation the detailed characteristics of the 82p33914-1 software and hardware components are described in other documents as shown in table 2 and table 3 . table 1: software options by root part number root part number included software 82p33914 idt clock recovery servo software 82p33914-1 idt clock recovery servo software ieee 1588 protocol stack table 2: software documentation software system component software documentation 82p33914-1 ieee 1588 software please contact idt table 3: smu hardware documentation root part number documentation 82p33914 82p33914-1 8 2p33814
