A compact optical lattice clock with a volume of 250 liters has been developed. The system includes a physics package for conducting spectroscopy on the clock transition within a vacuum chamber, ...

Industries such as metrology, aerospace and defense need ultra-stable timing for accurate data collection and reliable communication Adtran’s Oscilloquartz optical cesium clock now features the ESTU ...

The low-energy excited state of thorium-229 (229Th) isotope nucleus has recently gained much attention owing to it being an ideal candidate for ultra-precise nuclear clocks. Building such ...

Over on his secondary YouTube channel, [Jeff Geerling] recently demoed the new Mitxela Precision Clock Mk IV. This clock uses GPS to get the current time, but also your location so it can figure out ...

U.S. physicists have made a clock so accurate it will neither gain nor lose even a second in more than 200 million years, a finding sure to please even the most punctually minded. The clock, described ...

The Si5321 Sonet/SDH precision clock multiplier IC is targeted at OC-48, OC-192, OC-768, and 10 Gigabit Ethernet designs. Supporting the G.709 spec, this IC locks to a 19, 29, 78, 155, 311, or 622 MHz ...
