DESCRIPTION

IEEE 1588-2008 Precision Time Protocol (PTP) is a packet-based syn-

chronization mechanism used in packet-switched networks. PTP synchro-

nizes the clocks of different devices with the most accurate clock on the

network – usually a precise, grandmaster clock, such as one using a Pri-

mary Reference Time Clock (PRTC) time signal. The 82P33910-1 is a soft-

ware and hardware system that can operate as a PTP slave or PTP

master. As a PTP slave the 82P33910-1 recovers accurate and stable

electrical synchronization signals from a packet based reference gener-

ated by a PTP master. As a PTP master the 82P33910-1 can lock to a sta-

ble electrical clock source and generate packet based PTP references for

downstream PTP slaves
