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 ...

Data converters are critical elements in communication systems forming bridges between analog transmission media such as fiber optics, microwave, RF, and digital processing blocks such as FPGAs and ...

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 ...

Among many deliberations when designing with high-speed analog-to-digital converters (ADCs), the effect of the ADC’s sampling clock is paramount to meeting specific design requirements. There are ...

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 ...

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

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 ...
