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
