The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...

Scientists from Xinjiang University in China have allegedly developed a new ultraviolet (UV) producing crystal ...

Physicists are getting closer to creating a long-sought ‘nuclear clock’. This device would keep time by measuring energy ...

Physicists report creating a time crystal with unprecedented detail, showing stable oscillations without energy loss. The ...

Keeping perfect time is far trickier than it sounds. The world’s best clocks that are used for GPS navigation, satellite communication, and testing fundamental physics depend on carefully controlled ...

The next generation of atomic clocks "ticks" at the frequency of a laser. That is around 100,000 times faster than the microwave frequencies of the caesium clocks that currently generate the second.

An electronic system requires a reliable, precision timing reference: the system clock. We examine and compare two forms of system clocks, the Crystal Oscillator and the Phase Locked Loop Synthesizer ...

Building a crystal clock source for a CPU used to be a bit of an effort but these days, there’s nothing to it. Even if your CPU or other device needs an external clock, you just slap in an inverter, a ...

Measuring 2.5 x 2.0 x 0.9 mm, the NZ2520 crystal clock oscillator is claimed to be the industry's smallest and thinnest such part. The SMT-packaged oscillator is available in frequencies from 1.5 to ...
