Frequency References
The world runs on Symmetricom time
Atomic physics sets the standard for stability, accuracy and range of application in precision frequency reference packages worldwide. Our hydrogen, cesium and rubidium standards, and quartz oscillators support more military communications, satellite ground stations, and test & measurement applications than any other precision frequency references in the world. Our Chip Scale Atomic Clock (CSAC), the world’s smallest atomic reference, achieves historic breakthroughs in size, weight and power consumption.Advanced research, cutting edge electronics engineering, superior manufacturing, and integrated software design all result in precision frequency standards that deliver exceptional performance and unsurpassed accuracy, stability and reliability in the most challenging environments.

Chip Scale Atomic Clock (CSAC)
The world’s first chip scale atomic clock, the SA.45s CSAC measures less than 16cm3 cc in volume, is only 0.45 inches high, weighs just 35 grams and consumes a mere 125mW of power. Such breakthrough performance opens up an entirely new classes of portable applications such as marine geophysical sensors, backpack IED jammers, backpack military radios, unmanned aerial vehicles (UAVs) and military GPS receivers.
