In an atomic clock, the frequency of the quartz oscillator is fine tuned to match the energy needed to pop electrons to a new energy level.

On the Deep Space Atomic Clock, this correction is calculated and applied to the quartz oscillator every few seconds. But that's not all that makes the Deep Space Atomic Clock special.

This is the case whether we are describing a wristwatch with a quartz crystal oscillator or an atomic clock whose oscillator is made up of atoms undergoing quantum energy transitions. A crystal ...

Designers have implemented traditional clock sources with quartz-crystal resonators, but MEMS and pure-silicon resonators are gaining a foothold in this highly diverse market. In addition, less ...

Optica – Tight real-time synchronization of a microwave clock to an optical clock across a turbulent air path For greater phase coherence at Fourier frequencies beyond the effective synchronization ...

DSAC technology uses the property of mercury ions’ hyperfine transition frequency at 40.50 GHz to steer the frequency output of a quartz oscillator to a near-constant value. The clock confines the ...

They are so precise that a clock like the Deep Space Atomic Clock is estimated to take 10 million years to lose 1 second of accuracy. Rugged enough to survive space travel while also stable enough ...

Almost every electronic product needs a clock to provide its 'heartbeat' and, traditionally, this heartbeat has been supplied by a quartz oscillator. While there is nothing wrong with the basic ...

IDT is promising 50 ppm parts by 2011, but has been quietly seeding OEMs with advance models of its current 100 ppm IDT3C02 oscillator, which is already replacing quartz crystals in a wide variety of ...
