PCB Assembly GNSS GPS Disciplined Oscillator 10 MHz Frequency Reference NR4400-O/G

PCB Assembly GNSS GPS Disciplined Oscillator 10 MHz Frequency Reference NR4400-O/G

• GNSS-disciplined 10 MHz frequency reference with precision stability
• 26-channel high-sensitivity multi-GNSS receiver (GPS, GLONASS, QZSS, SBAS)
• Provides 10 MHz output, 1PPS and NMEA outputs (RS232-level NMEA option)
• Low phase noise performance suitable for precision timing applications
• Supports TRAIM, active anti-jamming and advanced multipath mitigation
• Auto-calibration with stored compensation coefficients for drift compensation
• Single 5 Vdc supply for simplified system integration (DC powered)
• Status signals for BIT, GNSS loss and system signal monitoring
• Compact embedded PCB assembly for easy integration into master timing systems

Ideal for system integration into telecom and radio networks, timing servers, test & measurement instrumentation, data centers, and embedded designs requiring a low-noise, precision 10 MHz reference with PPS and NMEA. The NR4400-O/G simplifies integration with a single 5 Vdc supply and on-board status signaling for robust master timing.

FAQ

1. Q: What power and integration requirements does the NR4400-O/G have?
   A: The module is DC powered from a single 5 Vdc rail to simplify system integration and minimize external power components.
2. Q: Can the unit provide NMEA at RS232 levels?
   A: Yes — NMEA output is standard and an RS232-level NMEA option is available for systems that require it.
3. Q: How does the product handle GNSS signal disturbances?
   A: The NR4400-O/G uses TRAIM, active anti-jamming, multipath mitigation and stored auto-calibration coefficients to maintain timing stability during signal anomalies.
