1PPS Disciplined 10 MHz Frequency Reference NR6720-PPS


Modular 1PPS Disciplined Frequency Reference

The NR6720-PPS locks a low noise OCXO to an external 1PPS signal. The 1PPS signal can be 3.3 or 5 Volt CMOS.  The disciplined oscillator features auto-calibration so that the most recent coefficients to compensate the OCXO for drift due to aging and/or temperature are stored and applied to the OCXO during GNSS GPS loss of lock conditions. The unit operates from a nominal 12 Vdc power source or available AC power adapter. Unit can be configured to operate from -60 to +60 Vdc in three ranges.

  • Holdover stability of 5 ppb/day,  50ppb/year.
  • PPS stability option- P-P jitter < 700 ps.
  • Locked accuracy <4E-11.
  • Available -60 to +60 Vdc in 3 ranges.
  • Indicators and signals provide GPS/GNSS lock and unit self-test status.
