Moving From 28 Gbps NRZ to 56 Gbps PAM-4: Is it a Free Lunch?

September 24, 2018 | Yuriy Shlepnev, Simberian

The usual way of signaling through PCB interconnects is a two-level pulse, an encoding of 1s and 0s or bits, named NRZ (non-return-to-zero) or PAM-2 line code type. Increasing the data rate with the NRZ code type presents some obstacles. For a 28 Gbps NRZ signal, the bit time is about 35.7 ps with the main spectral lobe below 28 GHz. For a 56 Gbps NRZ signal, the bit time is about 17. 86 ps, with the main spectral lobe below 56 GHz. One can feel the problem already: Getting PCB interconnect analysis and measurements up to 56 GHz and beyond is very challenging, to say the least.

Judy Warner: AltiumLive’s Second Year to be Even Better Than First

September 19, 2018 | Andy Shaughnessy, Design007

Last year, Altium launched its AltiumLive event with shows in San Diego and Munich, Germany. This year, the event has expanded to include an extra day of classes. Altium is gearing up for the San Diego event in early October and the German show in January 2019. I recent spoke with Judy Warner, director of community engagement for Altium, about what designers should expect at both shows, and how the company can build on the success of the 2017 events going into the future.

The Shaughnessy Report: The Whole Package

September 19, 2018 | Andy Shaughnessy, I-Connect007

When we started planning this issue, I found an interesting tidbit of information: Electronics packaging predates the printed circuit board. Most electronics history buffs seem to agree that the Braun Tube of 1897, the forerunner of...
