Timing & Frequency

Brandywine PTP Slave Network Time Client
Product Overview
  • Delivers highly economic end-to-end frequency synchronization
  • Frequency accuracy better than 10ppb possible using Giga bit switches
  • Precision timing circuits ensure stability in event of synchronization signal interruption
  • Client system time accuracy better than 1 microsecond using Giga bit switches
  • Configuration and alarm reporting capabilities using Simple Network Management Protocol (SNMP)
  • Time of Day (TOD) is provided for support of legacy equipment using IRIG B and RS232


The PTP Slave provides a high performance synchronization clock solution (SETS) for use in SDH/SONET back haul applications or as a replacement system, allowing for synchronization over packet switched networks (PSN). The PTP Slave Network Time Client also provides time distribution using PSN, IRIG B and RS232. This is done using Precision Time Protocol (PTP) over an Ethernet network.

System Benefits

  • Powerful network delay analysis delivers full time alignment over hostile networks (including Layer 2 and Layer 3 routing)
  • Configured or automatic best master clock selection
  • No need for antennas (GPS)
  • E1 ITU G.703 synchronization clock signal is configurable via user menus
  • Unicast operation ideal for use in Telecoms environment


The PTP Slave is available as a board-level product, as a rack-mountable unit or as a stand alone unit.

Module connections

The unit provides two standard RJ45 connections to a 100BASE-T network. One for configuration and firmware uploads and the other for PTP connection to the master PTP clock. A 9 way D type socket is also available for RS232 connection for configuration, status and firmware upload purposes (115.2kbaud, 8 bit characters and 1 stop bit). 1PPS and 10MHz outputs are provided via two BNC 50Ω sockets. E1 output via 75Ω BNC socket and RJ45 connection.
