With the growth of 5G data traffic and AI computing, data centers need faster connectivity to meet the increasing bandwidth. High speed I/O speed beyond 112 Gb/s per lane is required. If we follow the SerDes technology revolution by doubling the data rate per lane in every 2-3 years, the next generation I/O data rate will be 224 Gb/s. In this article, Cathy Liu explores options, technical challenges, and potential solutions to achieve 224 Gb/s per lane.

I often get questions from my fellow design engineers from around the world asking why we should or should not use S parameters or Z parameters for power distribution network (PDN) designs or validation.  The truth is, we should be familiar with both, because depending on our design and validation tools, one or the other may be better suited for the task. Read on to find out why.

Keysight Technologies, Inc., has launched a portfolio of Smart Bench Essentials (SBE) lab bench products that deliver the power of four instruments, including a triple-output power supply, an arbitrary function generator, a digital multimeter and an oscilloscope, through one powerful graphical interface offering integrated data management and analysis capabilities.

While many already had home lab setups for projects and exploring curiosities, the challenges of the global pandemic have driven many to ramp up their set ups and spend more time at their in-house benches. Over the years, Signal Integrity Journal has worked with many leading industry experts and stars in our field. Some have gamely agreed to play along with me and share images of their home labs. Enjoy the tour!

If you are missing your engineering tools, or would like to build up your home lab, or want to finally work on that hobby electronics project you’ve put off for the last five years, or you want to introduce your kids to the thrill of measuring or simulating, now would be a good time to consider our list of free or very low-cost hardware and software simulation tools.

Measuring low impedance components with a 2-port vector network analyzer (VNA) is an essential technique that typically requires a VNA that costs more than $20,000. In this article, see how the authors measured an MLCC using $500 and an open-source simulation tool.

Sometimes, when SI and PI worlds collide, we get the best of both worlds. By borrowing a simple impedance measuring technique from the PI world, we have another tool at our disposal to measure true characteristic impedance from a uniformly designed transmission line in the SI world, read on to learn more.

In response to the continuing challenges caused by the global pandemic, the organizers of EDI CON CHINA have decided to change the program for 2021 to ensure timely delivery of technical conference material to engineers across the country. Today, Horizon House announced that instead of a large in-person event this year, EDI CON CHINA 2021 will occur as EDI CON ACROSS CHINA 2021, which will include a virtual event paired with localized in-person conferences throughout China.

Recently, Ansys released its HFSS Mesh Fusion product for simulation of complex EM systems. Signal Integrity Journal (SIJ) followed up with Dr. Matthew Commens, Principal Product Manager, HF at Ansys, Inc., to find out some more details.

EDI CON Online, an interactive event that was held every Tuesday in October 2020, provided training and keynote sessions for engineers working in RF, microwave, EMC/EMI, signal integrity, and power integrity. The event held live online sessions that are still available to watch on demand, presented notable results with more than 7830+ sessions viewed and 6400+ unique registrants to date.
