SA.45s Chip Scale Atomic Clock (CSAC)

Eletter Product


For the first time...

The accuracy and stability of an atomic clock is now available in a small, low power oscillator.

At only 0.45 inches high, the SA.45s CSAC is the world’s first atomic clock with the small form factor and low power consumption portable applications demand. As a true atomic clock it surpasses crystal oscillators (OCXOs and TCXOs) by wide margins in initial accuracy, aging, and temperature coefficient. It brings autonomous, reliable timekeeping to applications for which an atomic clock would not have previously been considered due to space and/or power constraints.

The SA.45s Chip Scale Atomic Clock (CSAC) provides the accuracy and stability of atomic clock technology while achieving dramatic reductions in size, weight and power consumption. This newest member of Symmetricom’s QUANTUM™ family of atomic oscillators is ideal for applications, especially those in GPS-denied environments,  that call for precise synchronization, accurate time keeping and maximum portability. It is only 16cc in volume, weighs only 35 grams, requires only 115mW of power and provides time accuracy two orders of magnitude better than the quartz-based solutions it replaces, such as Oven-Controlled Crystal Oscillators (OCXOs) and Temperature Compensated Crystal Oscillators (TCXOs).
