10 MHz Self Calibrating-TCXO Based

Category: References

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

NR3700-CAL-T

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
