The Next Generation of Timing & Frequency


Small, low power GPSDO.

FireFly(tm) is an extremely small Global Positioning System Disciplined Oscillator (GPSDO) that has very low power consumption, delivers long-term performance similar to Atomic Frequency Standards, and supports mobile as well as stationary applications.

At only 1.25 Cubic Inches small, FireFly provides Stratum-1 long-term performance of better than 10 parts per Trillion (1E-011) averaged over 24 hours when locked to GPS at less than ½ the size of the smallest competitive products. The unit generates both an OCXO-driven 1PPS output that is phase-synchronized to better than 100ns rms to UTC, and a synchronized low-noise+12dBm 10MHz Sine-Wave Output. The FireFly is easy to integrate in any application requiring a stable and accurate reference clock, and can be monitored and controlled by an RS-232 port via industry-standard SCPI Commands. FireFly has excellent phase noise, superior spurious suppression, and very low jitter at a power consumption of only 1.4W typically.

FireFly-1A options

The FireFly-1A can be ordered with the following options:
  • Operating temperature range: 0°C to +60°C (standard range).
  • Operating temperature range: -40°C to +70°C (extended range).
  • 6V power supply option.
