NTP100-OSC Time Server


The NTP100-OSC NTP time server synchronizes 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.




  • NTP output accuracy of ± 2 ms
  • Time synchronized 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



Holdover Accuracy  
After initial input of time,  the NTP100-OSC will typically maintain accuracy of ± 1 min/year using standard internal precision TCXO temperature-compensated crystal oscillator
High-stability option with OCXO provides typical stability of 1 ppb/day (± 250ms/year)  
NTP reference for query (Unicast), Multicast, or Broadcast mode – user definable
