NTP100-OSC

Stand-alone NTP server with internal precision temperature controlled crystal oscillator.


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)  

Outputs  

  • NTP reference for query (Unicast), Multicast, or Broadcast mode – user definable

Rack Mount

  • Optional RM4 rack mount kit available

Connectors  

  • RJ45 ─ 10/100 MB
  • DC input ─ 2.1 mm male jack  
  • RS-232 ─ 9 pin male
