Pairing Radiation Tolerance with the CSAC’s Low Power and High performance – brings the accuracy and stability of atomic clocks to Commercial Space applications.

The Microsemi Commercial Space CSAC is the world’s first commercially available radiation-tolerant chip scale atomic clock, providing the accuracy and stability of atomic clock technology while achieving true breakthroughs in reduced size, weight and power consumption. This product is ideal for Low Earth Orbit applications. (Part Number 090-02984-007)

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 that require radiation tolerance, such as:

● Low Earth Orbit (LEO) commercial satellites
● Military systems including dismounted IED jammers, dismounted radios, GPS receivers, and unmanned aerial vehicles (UAVs)
● HW platform to evaluate CSAC
● On board socket for CSAC
● HW included to allow mounting of evaluation board
● Wall socket power supply
● RS-232 cable to connect PC to evaluation board
