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 ...

With an eye on the handheld market, the lead-free NZ2520 series crystal clock oscillators are described as the industry's smallest and thinnest. Their surface-mount packages measure 2.5 mm x 2 mm with ...

This Design Idea describes an inexpensive circuit to generate two extremely high-quality, crystal-clock-reference-signals, one of which is a PWM-controlled VCXO (voltage-controlled crystal oscillator) ...

Imagine a clock that will keep perfect time forever or a device that opens new dimensions into the study of quantum phenomena such as emergence and entanglement. Researchers have proposed a space-time ...

Quantum timekeeping has reached a new threshold, with trapped-ion clocks now accurate to the 19th decimal place and a separate line of theoretical work suggesting that time crystals, exotic quantum ...

Scientists say that a perpetual motion machine is physically impossible, but a research team at the University of California Berkeley has just outlined an idea that comes pretty damn close. By ...

http://www.cardinalxtal.comThe term “frequency jitter” has become popular in the last few years to define the short-term stability of a frequency source. A ...
