The SA.45s Chip-Scale Atomic Clock – Early Production Statistics

Robert Lutwak

Abstract:	Since the announcement of general availability of the SA.45s Chip-Scale Atomic Clock (CSAC) on January 18, 2011, Symmetricom has been ramping up production in order to meet customer demand for this new and disruptive technology. The SA.45s is the first commercially available CSAC, with power consumption of less than 125 mW and short-term stability of ?y(t)2 x 10-10/t1/2. This paper will report early production statistics of SA.45s performance including power consumption, short-term stability, and temperature sensitivity. Environmental susceptibility measurements of production devices will also be presented, including mechanical shock, vibration, and total-ionizing dose radiation exposure.
