Timing & Frequency

Brandywine IEEE-1588 PTP80 Grand Master Clock
Product Overview
  • Uses Precision Time Protocol (PTP) to IEEE-1588 v2
  • Distributes time to remote PTP clients and slaves over a network
  • Advanced hardware-generated timestamps
  • GPS input source
  • Provides ±100 nanosecond timing accuracy (when locked to GPS)
  • Internal disciplined oscillator provides stability if input source interrupted
  • Choice of outputs include 1PPS & 10MHz (IRIG-B & E1/T1 optional)
  • 19 inch 1U high rack mountable chassis
  • The PTP80 Grandmaster Clock generates and distributes precisely synchronized time across Ethernet networks.


Precision Time Protocol (PTP), described in the IEEE 1588-2008 version 2 standard, allows for extremely precise synchronization of networks. An absolute timing accuracy of better than 100 nanoseconds to UTC can be achieved using this protocol as it uses hardware-generated timestamps. This provides significant improvements on the accuracy of network-distributed time over legacy Network Time Protocol (NTP) servers.

The PTP80 uses an internal oscillator (OCXO as standard, factory upgradeable to Rubidium) disciplined by an integral GPS receiver as a highly stable time base. The use of precision oscillator options provides improved stability in holdover mode if the input source is interrupted for any reason.

The front panel has a large alphanumeric LCD, status indicator and 5-segment button for easy status and minimal configuration. The main configuration and monitoring is through a secondary network port providing web access. A range of additional output options are available, including serial, pulse, timecode and frequency - please contact our sales support team for more information.
