10 MHz GNSS Disciplined Frequency Reference with Stabilized PPS PCB Assembly-NR4430-O/G

10 MHz GNSS-Locked OCXO Based Frequency Reference PCB Assembly
– Digital Control Loop Enables Low Jitter PPS and Low Close in Phase Noise

NR4430-O/G

 

Compact 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. Digital control loop provides low close-in phase noise and pulse-t0-pulse jitter on the PPS of less than 1 ns. Auto-calibration stores the most recent compensation coefficients – dramatically minimizing long-term drift. Single 5 Vdc power supply simplifies system integration. Status signals alert the system to BIT failures or loss of GNSS signal. See the attached white paper on GNSS reference design notes.

  • 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.
  • PPS p-p jitter < 1 ns.

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.
