Product Information

Atomic clock accuracy and low power make the SA.45s ideal for portable applications requiring precise synchronization and time keeping, especially in GPS-denied environments.

Breakthrough Leadership The CSAC’s unmatched portability derives from specs that include:

  • 115mW power consumption
  • 16cm3 volume
  • 35g weight
  • ±5.0E-11 accuracy at shipment
  • σy < 5 x 10-12 at τ = 1 hour short-term stability (Allan Deviation)
  • <3.0E-10/month aging rate

A New Class of Applications At two orders of magnitude better accuracy than oven-controlled crystal oscillators (OCXOs) — and up to four orders of magnitude better accuracy than temperature-controlled oscillators (TCXOs) — the CSAC’s unmatched portability opens the door to new classes of applications, such as:

  • Underwater sensors for seismic research or gas and oil exploration
  • Military systems including dismounted IED jammers, dismounted radios, GPS receivers, and unmanned aerial vehicles (UAVs)

Device Connectivity The SA.45s CSAC produces two outputs, a 10MHz square wave and 1PPS, both in a CMOS 0 – 3.3V format. It also accepts a 1PPS input for synchronization and provides an RS-232 interface for monitoring and control.
