10 MHz TCXO GNSS Locked Frequency Reference PCB Assembly-NR4400-T

10 MHz GNSS-Locked TCXO Based Frequency Reference PCB Assembly – PPS, NMEA with Auto-Calibration – Low Cost TCXO


Compact TCXO based GNSS-locked reference designed to be easily integrated into your system to provide precision 10 MHz, PPS and NMEA for master timing. The unit features a 26 channel high-sensitivity, high-accuracy multi-GNSS receiver. Supports TRAIM, GPS, GLONASS, QZSS, SBAS, Active Anti-Jamming and Advanced Multi-path Mitigation functions. Auto-calibration stores the most recent compensation coefficients – dramatically minimizing long-term drift. Single 5 Vdc power supply for convenient system integration. Status signals alert the system to BIT failures or loss of GNSS signal. A low cost alternative to an OCXO based reference for less demanding phase noise applications.

  • 26 channel GNSS receiver.
  • Simple integration requires only a single 5 Vdc power supply.
  • NMEA at full RS232 levels (logic levels available option)
  • Status signals alert of a long-term GNSS loss.
  • Low phase noise.
  • Frequencies to 100 MHz available.
  • Power consumption < 1 Watt.

    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.
