Digital Control Loop Enables low Jitter PPS and Low Phase Noise

Compact GNSS locked reference designed to be easily integrated into your system to provide precision 10 MHz, PPS and NMEA for master timing. The unit features a 26 channel high-sensitivity, high-accuracy Multi-GNSS receiver. Supports TRAIM, GPS, GLONASS, QZSS, SBAS, Active Anti-Jamming and Advanced Multipath Mitigation Functions. Digital control loop provides low close in phase noise and pulse t0 pulse jitter on the PPS of less than 1 ns. Auto-calibration stores the most recent compensation coefficients dramatically minimizing long-term drift. Single 5 Vdc power supply simplifies system integration. Status signals alert the system to BIT failures or loss of GNSS signal. See the attached white paper on GNSS reference design notes.

• Simple integration requires only a single 5 vdc power supply.

• NMEA at full rs 232 levels (logic levels available option)

• Status signals alert of a long-term GNSS loss.

• Low phase noise

• Frequencies to 100 MHz available.

• PPS jitter < 1 ns
