I have been experimenting with passive crystal oscillators for over two decades, but while looking around, came across some great articles on active crystal oscillators. Last year I got a few ...

The crystal oscillator “offers phase noise at 10Hz [of ... clock’s features and plot their operating parameters”, said Microchip. Find the atomic clock product page here, and an informative user guide ...

The LN-CSAC combines the benefits of a crystal oscillator and an atomic clock in a single compact device. The EMXO offers low-phase noise at 10 Hz < -120 dBc/Hz and Allan Deviation (ADEV) stability ...

If needed, the system can “rescue” a disrupted crystal by cooling it, reforming its shape, or breaking apart molecules formed during background gas collisions. Taming the laser: how the clock ...

For this purpose, this new ion crystal clock was compared with other optical clocks and a new accuracy record was achieved. The PTB researchers report their in Physical Review Letters. An undisturbed ...

The National Institute of Standards and Technology's new cesium fountain clock is one of the most precise atomic clocks ever ...

In 2001, physicist Ekkehard Peik first became excited about building a nuclear clock based on the nuclear pulse of thorium-229, a radioactive by-product of the decay of uranium-233. “We were ...
