NTP100-OSC Time Server


Overview

Network Time Protocol (NTP) Server 

The NTP100-OSC NTP is a stand-alone time server that synchronises to a TCXO (temperature-compensated internal oscillator) and sends NTP reference signals to NTP devices via Ethernet, maintaining an accuracy of ± 1min/year or < 165ms per day.

An optional OCXO increases stability to ± 250ms/year.

Technical

  • NTP output accuracy of ± 2 ms
  • Time synchronised to internal precision temperature compensated crystal oscillator (TCXO)
  • High-stability option with OCXO provides typical stability of 250ms/year
  • NTP unicast, multicast or broadcast modes
  • Assignable network configuration
  • Configuration via Telnet/SSH or included WinDiscovery
  • IPv4/IPv6 compatible
  • MD5 authentication
  • Time stamp precision/resolution of 5-10ms

Specifications

Holdover Accuracy

  • Internal precision TCXO temperature-compensated crystal oscillator provides accuracy of ± 1min/year or < 165 ms/day
  • High-stability option with OCXO provides typical stability of 1 ppb/day (± 250ms/year) after 30 days of aging
 

Connectors

  • RJ45 - 10/100MB Ethernet
  • DC input - 2.1 mm male jack
