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.

Four Channel 1PPS source NR3623-PPS

Four Channel PPS Source with NMEA

Three < 1 ns Skewing Channels and a Fourth Reference Channel


Four transient and fault protected PPS outputs with < 1 ns of channel skewing. Each channel is monitored and status LED’s displayed on the front panel. Built-in self-test drives a signal that can be tied into an alarm panel. High performance GNSS receiver offers 26 channels for rapid acquisition. Programmable pulse width and cable compensation,

  • Four fault and transient protected outputs.
  • Operates from an AC power adapter or from a DC source from  -60 to +60 Vdc (in three ranges).
  • Channel skewing < 1 ns ( Skewing is typically less than 200 ps on the three BNC channels)
  • Drives 3.3 Vdc or 5 Vdc LVCMOS into 50 Ohms on the three BNC channels, 5 Vdc CMOS into 1000 Ohms on SMA Channel.
  • 1PPS accuracy < 30 ns  rms.
  • RS232 NMEA data.

    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.
