PCIe has been around since 2004. It’s a high-speed serial computer expansion bus specification that replaces older PCI and PCI-X standards. PCIe currently supports the Generation 4 specification. In ...

Physicists have demonstrated an experimental, next-generation atomic clock -- ticking at high 'optical' frequencies -- that is much smaller than usual, made of just three small chips plus supporting ...

The newest atomic clock works on optical frequencies that are higher than the microwave frequencies used in the previous generation. Physicists at the National Institute of Standards and Technology ...

first half wave and a second half wave representing the received RF signal.

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

Races, missed next-state values due to long paths, and metastability can result from corrupted clock signals. This post describes the challenges of clock network and clock jitter analysis in more ...

The move to 400GbE has benefits beyond the obvious fact that it's four times faster than 100GbE. The standard provides a lower price-per-port from its denser structure and improved economy of scale. A ...

In a rock band, the drummer keeps the beat steady and the other musicians follow the rhythm. The drummer keeps the entire band in sync. The same concept is true when you integrate multiple instruments ...
