Synchronization System
for IEEE 1588
82P33913 / 82P33913-1
Datasheet
Description
The IEEE 1588-2008 Precision Time Protocol (PTP) is a
packet-based synchronization mechanism used in
packet-switched networks. PTP synchronizes the clocks of
different devices with the most accurate clock on the network –
usually a precise, grandmaster clock such as one using a Primary
Reference Time Clock (PRTC) time signal.
The 82P33913-x is a software and hardware system that can
operate as a PTP slave or PTP master. As a PTP slave, the
82P33913-x recovers accurate and stable electrical
synchronization signals from a packet-based reference generated
by a PTP master. As a PTP master, the 82P33913-x can lock to a
stable electrical clock source and generate packet based PTP
references for downstream PTP slaves.
The 82P33913-x is available with the two software options listed
in Table 1.
