In Donald Telian’s book he reveals his steps for successful serial links, called the “7 Steps to Successful Serial Links.” In this article, he discusses his most important steps: (one) minimize discontinuities, and (two) manage loss.  

Modern ASIC-based systems can no longer be designed by rules of thumb when it comes to power integrity. In this DesignCon 2022 paper, Ben Dannan et al explain a workflow using lumped-looped models to improve efficiency, while achieving accuracy, and reducing the overall risk to a given system PDN.  

This article shows the impact of using one of the first DDR4-3200 FPGA memory controllers, the Xilinx Versal, interfaced to a UDIMM to show a method for accurately correlating signal integrity simulations to measurement.

In this article, Eric Bogatin uses the issue of power integrity to illustrate why dialog between experts is crucial. 

In this installment of Practical EMC, Ken Wyatt reviews real-time spectrum analyzers, helping you to pick the one best suited to your needs and within your price range.

In this power-electronics article, we focus on noise measurement of 48 V range voltage regulators (VRs), up to a maximum of 65 V. We propose a noise measurement setup and examine this method.

About 150 years ago the first stable transatlantic cable was laid and messages were sent between Ireland and Newfound­land over copper. The data rate on this cable was not even 1 bit/sec, it was 0.1 bit/sec. Concerns over the cable reliabil­ity and the slow data rate led some to believe copper was doomed as a communication media for these long cables.

In part one of this article, Bert Simonovich explained how air entrapment is the primary reason for Dkeff and phase delay discrepancies between simulation and DUT measurements. Read on to discover how to fix this issue.

In this edition of Practical EMC, Ken Wyatt walks you through different spectrum analyzers and his experience with them, helping you to pick the one best suited to your needs. 

Since the inception of IBIS, the IBIS Committee has been working to improve and accommodate limitations of the model. This article gives a synopsis of that history, along with detailing the latest version, IBIS 7.1.
