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 ...

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 ...

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 ...

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 ...

Occasionally you might need a simple clock module for various projects. A small CMOS clock module, such as the one presented here, is not capable of offering as much precision as a clock module built ...
