Spread spectrum technology has blossomed from a military technology into one of the fundamental building blocks in current and next-generation wireless systems. From cellular to cordless to wireless ...

We're here to settle, once and for all, the pros and cons of spread-spectrum clocking as an EMI countermeasure. In case you're unaware, many systems today employ frequency-modulation of their clock ...

Many of us who work primarily in digital verification and design are shielded from physical layer details. Only a handful of specialists closely follow these details. So for the rest of us, verifying ...

Spread spectrum clocking (SSC) is used in many computer interfaces such as PCI Express and Serial ATA to improve the EMI performance of the interface. It takes the form of frequency modulation (FM) of ...

A new technical paper titled “Clock-to-Clock Modulation Covert Channel” was published by researchers at University of Rennes-INSA Rennes-IETR-UMR and University of South Brittany/Lab-STICC- UMR CNRS. ...

Conducted and radiated EMI emissions from switchmode power supplies can create havoc with nearby electronic systems. Alliance Semiconductor has developed a lower cost all-electronic approach for EMI ...
