10 MHz Frequency References – OCXO, TCXO and Rubidium Based. GNSS-Locking Provides Long-Term Stability

Novus offers a range of GNSS GPS disciplined oscillators and related reference products. While our most  popular frequency reference is 10MHz, many of our products are available at 50 and 100 MHz. Unique frequencies are available as well. Novus references can be OCXO , TCXO or Rubidium based. GNSS-locking enhances long-term stability.  Stability options are available that incorporate vibration and thermal isolation. Our reference products are available in 19 inch rack mount and modular, chassis.  Our miniature PicoPod series fits almost anywhere.  Novus reference distribution amplifiers offer minimal phase noise contribution and skewing.  Novus PPS sources can be synchronized to a 10 MHz reference to provide a complete timing solution.  Our PPS sources can be directly from a GPS PPS source or processed to improve jitter and statistical accuracy. For GNSS denied environments,  Novus offers a range synthesized 1PPS sources.   Our PPS distribution amplifiers offer sub 1 nsec skewing and transient and fault protection. For enhanced control and monitoring, SNMP and local control are available as options. Portable reference products offer excellent holdover stability to provide accuracy in GNSS denied environments.

Six Channel 10 MHz, Six Channel PPS Simulator- OCXO based - NR3612-O

Six Channel 10 MHz and Six Channel PPS OCXO Based 10 MHz Frequency Reference

Six Channel Low Phase Noise Reference plus Six Channels of PPS Operates from-60 to +60 Vdc in Three Ranges or an AC Adapter


The NR3612 is a high performance 10 MHz frequency reference driven by a low noise SC cut, OCXO. The six 10 MHz outputs are 13 dBm and the 6 PPS outputs can be at 5 or 3.3 logic levels.  PPS outputs can drive 50 Ohm. External synchronization to 10 MHz or PPS.

  • Low phase noise OCXO.
  • 6 channels 10 MHz channels also available 50 MHz
  • 6 channels of PPS at 3.3 or 5 volt levels
  • Low close-in phase noise.
  • Hold-over stability of 5 ppb/day, 50ppb/year.
  • Operates from DC power in three ranges +- (10 to 18, 18 to 36, 36 to 65) VDC or an AC adapter.
  • Indicators and signals provide unit self-test and channel fault status.
  • RS232 port provides BITE and channel status.

Wide input power range (-60 to +60 VDC) in three ranges

    GPS DO Kits are available that include antenna, cables and power supply. Several features can be customized at the factory – frequencies other than 10 MHz either from a unique crystal or with a built-in synthesizer that is GNSS-locked. Time stamping capability to 100ns resolution. To meet unique requirements, we have shipped product with output features requiring a custom amplitude, square wave output, high voltage and high current drive.
