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.
