SA.3Xm

Miniature Atomic Clock

The SA.3Xm marks a major step forward in the evolution of rubidium atomic clocks: the world’s first commercially available miniature atomic clock. The SA.3Xm family has been designed to be suitable for applications requiring compact design, lower power consumption, and excellent aging and precision in an economical and easily adaptable package.

Symmetricom has leveraged significant advances in physics miniaturization and integration to design a form factor five times smaller than existing rubidium oscillators.

The SA.3Xm has the physical dimensions of a small ovenized crystal oscillator (OCXO), measuring 51mm X 51mm (2” X 2”), and standing at a mere 18mm (0.7”). It consumes little power and has wide-spectrum temperature operation. This makes it accessible to a wide range of timing and synchronization applications, from wireless base stations, to telecom networks to test and measurement devices.

The SA.31m is targeted for applications where an economical solution for frequency stability is required, such as UMTS (WCDMA). It can be used as an independent timing source for base stations, and enable transition from costly TDM backhaul transport to economic and efficient Ethernet transport.

The SA.33m is suitable for replacing existing rubidium oscillators in long holdover applications, such as CDMA.
