Atomic Clock Technology
Atomic Clock is a precise clock with an electrical oscillator regulated by the natural vibration frequencies of an atomic system, such as a beam of cesium atoms, ammonia atoms, or rubidium.
Atomic clocks are inherently more accurate than quartz clocks, because their source of oscillation depends on atomic characteristics, while quartz clocks depend on the precision of the manufacturing process used to create the quartz crystal. Quartz clocks also tend to vary more with temperature.

Microsemi Leadership in Atomic Clock Technology
On a weighted average basis, Microsemi atomic clocks provide over 90% of the input to Universal Coordinated Time (UTC). Microsemi is the world’s only commercial provider of cesium beam-tube clocks, used in national labs around the world. Microsemi is also the leading provider of gas-cell atomic clocks, including the Chip Scale Atomic Clock (CSAC), the world’s smallest and lowest-power atomic clock, and the Miniature Atomic Clock (MAC).
