NR4430 GNSS disciplined Reference with stabilized PPS

Category: PCB ASSEMBLY-PC104
SKU: NR4430-O-G

10 MHz GNSS Locked OCXO Based Frequency Reference PCB Assembly

Digital Control Loop Enables low Jitter PPS and Low 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 Multipath Mitigation Functions. Digital control loop provides low close in phase noise and pulse tp 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 rs 232 levels (logic levels available option)
  • Status signals alert of a long-term GNSS loss.
  • Low phase noise
  • Frequencies to 100 MHz available.
  • PPS jitter < 1 ns
