10 MHz Frequency Reference, Self-Calibrating, Single Channel GNSS Locked, TCXO

The NR3700-CAL frequency reference continously monitors the correction coefficients being applied to the TCXO to compensate for aging and temperature stability. The coefficients are stored in non-volatile memory and in the event of GNSS loss, are used to maintain the accuracy of the crystal - GPS loss offset +- 10 ppb.  A high performance low cost GPSDO for software defined radios-

  • Low phase noise TCXO

  • GNSS lock indicator and built in self test

  • Hold-Over stability of +-1 ppm/year

  • Self-Calibration minimizes frequency transition during GNSS lock to < 10ppb

  • Locked accuracy < 4E-11

  • Low phase noise

see demo video on YOUTUBE (NR3620)

  • Operates from DC Power in three ranges +- (10 to 18, 18 to 36, 36 to 65) VDC or an AC Adapter

  • PPS Accuracy 20 ns rms (optional)

  • Indicators and signals provide GPS Lock and unity self-test status

  • Available in Kit Form (Includes reference, antenna, 50' cable, and power adapter)

GPSDO Kit available, wide input power range (-60 to +60 VDC)
