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 ...

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 ...

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.

Most of us know that a quartz clock uses a higher frequency crystal oscillator and a chain of divider circuits to generate a ...

A small, paper-thin piece of synthetic quartz acts as the watch's oscillator. Think of the oscillator like the pendulum in a grandfather clock, that by its continuous motion tells the watch how ...

The low-jitter part, SiT8102, has less-than-1-psec-rms phase jitter in most measurement bands, comes in a 2.5×2×8-mm QFN package, and will cost less than a comparable quartz device. You can use it as ...

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 ...

Although products from only a few companies have been discussed in detail, the clock and oscillator market is huge, amounting to at least $3.2 billion in 2006, so it has attracted lots of attention.7 ...
