The NR3626 is a high performance 10 MHz frequency reference that is driven by a low phase noise SC cut OCXO disciplined by a 26 channel GNSS receiver.  The 10 MHz outputs are 13 dBm while the PPS outputs can be 5 or 3.3 Volt logic levels with the capability of driving a 50 Ohm load. UNit can be configured to lock to GNSS, an external 10 MHz, external PPS or 1300 nm fiber signal.

• Low phase noise OCXO.

• Six channels 10 MHz channels

• Low close-in phase noise.

• PPS drives loads including 50 Ohms.

• GNSS lock indicator and built in self test.

• Hold-over stability of 5 ppb/day, 50ppb/year.

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

• Locked accuracy < E-12.

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

• PPS Accuracy 25 ns rms (low jitter mode).

• Indicators and signals provide GNSS lock and unit self-test status.

Wide input power range (-60 to +60 VDC)
