The data is in for an atomic clock sent to space in 2019 and a JPL scientist explains what the Deep Space Atomic Clock means for the future of GPS and space travel.

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 ...

Do not be misled by its small size! Here is the schematic for the clock module circuit I developed: This is a standard CMOS clock oscillator circuit. What I wanted was a digital clock generator ...

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 ...

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 ...

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 ...
