Synchronization System
for IEEE 1588
82P33913 / 82P33913-1
Datasheet
Description
The IEEE 1588-2008 Precision Time Protocol (PTP) is a
Features
▪ System implements ITU-T telecom profiles
packet-based synchronization mechanism used in
▪ Composed of IDT’s IEEE 1588 software and IDT’s
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.
Synchronization Management Unit (SMU) hardware
▪ Operates as IEEE 1588 / PTP slave
▪ Recovers accurate and stable synchronization signals from
packet based IEEE 1588 / PTP master
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
▪ Provides integrated physical layer frequency support
▪ Operates as an IEEE 1588 / PTP master
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.
Software
▪ C99 source code distribution, supporting POSIX-based
Operating Systems (OSs) such as Linux
▪ IEEE 1588 compliant Precision Time Protocol (PTP) stack
The 82P33913-x is available with the two software options listed
in Table 1.
▪ Abstraction interface supports user-supplied IEEE 1588
compliant Precision Time Protocol (PTP) stack
Table 1. Software Options by Part Number
▪ Reference trackers filter packet synchronization noise from
IEEE 1588 unaware networks

▪ Carrier Ethernet switches
▪ Multiservice access platforms
▪ PON OLT
▪ Digital PLLs can be configured as Digitally Controlled
Oscillators (DCOs) for IEEE 1588 clock synthesis
▪ LTE eNodeB
▪ Generates G.8262 compliant SyncE clocks
▪ ITU-T G.8265.1 and G.8275.1 Telecom Profile clock
▪ Fractional-N input dividers support a wide range of reference
synthesizer
frequencies
▪ ITU-T G.8273.2 Telecom Boundary Clock (T-BC) and Telecom
▪ Time Slave Clock (T-TSC)
▪ Locks to 1 pulse per second (PPS) references from GPS based
sources
▪ Loads configuration from an external EPROM after reset
▪ ITU-T G.8264 Synchronous Equipment Timing Source (SETS)
▪ ITU-T G.8263 Packet-based Equipment Clock (PEC)
▪ ITU-T G.8262 Synchronous Ethernet Equipment Clock (EEC)
▪ ITU-T G.813 Synchronous Equipment Clock (SEC)
▪ Telcordia GR-253-CORE Stratum 3 Clock (S3) and SONET
Minimum Clock (SMC)
