100 MHz Frequency Reference, Self-Calibrating, Single Channel GNSS Locked, OCXO

The NR3620-100 frequency reference continously monitors the correction coefficients being applied to the OCXO to compensate for aging and temperature stability. The coefficients are stored in non-volatile memory and in the event of GPS loss, are used to maintain the accuracy of the crystal - GPS loss offset +- 10 ppb. 

  • Low phase noise OCXO

  • GNSS lock indicator and built in self test

  • Hold-Over stability of 7ppb/day

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

  • Locked accuracy < 4E-11

  • Low phase noise
