Redefining the second: Optical atomic clock achieves record accuracy in comparison measurement

The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the microwave frequencies of the cesium clocks which are generating the second at ...

PLL clock generation IC replaces crystal oscillators for clock generation

The NB4N507A is the first in a series of fully-integrated phase lock loop (PLL) ICs designed to replace expensive crystal oscillators for clock generation in a wide variety of consumer and networking ...

System Clock Generators: A Comparison of a PLL Synthesizer vs. a Crystal Oscillator Clock

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 ...

New optical atomic clock is 1,000x more accurate than today's standard

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 ...

Optical atomic clock achieves record accuracy redefining the second

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.
