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 10MHz Disciplined Oscillator in PC104 Form Factor with 1PPS and NMEA-NR4600-O/G

PC104 Six Channel 10MHz GNSS GPS Disciplined Oscillator with 1PPS and NMEA

Compact Six Channel Frequency Reference


Six independent 13 dBm 10MHz sine outputs that are fault and transient protected and individually monitored. Channel status available over RS232 port. NMEA -0183 port at full RS232 levels or 3.3 Vdc logic. PPS at 3.3 Vdc  Only a single voltage power source required. The unit also features auto-calibration that compensates for long-term crystal drift to provide years of precise performance. There is also a GNSS GPS lock status signal, 1PPS and serial port to provide access to NMEA  and equipment status.

  • 26 channel high-sensitivity, high-accuracy multi-GNSS receiver. Supports TRAIM, GPS, GLONASS, QZSS, SBAS, Active Anti-Jamming and Advanced Multi-path Mitigation functions.
  • PC104 compliant mechanical design.
  • Operates from -60 to +60 Vdc power in three ranges.
  • Auto-calibration minimizes long-term drift.
  • GPS DO with active antenna

    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.
