The new connectors feature robust construction and superior EMI filtering capabilities, ensuring optimal performance and reliability in the most demanding environments.

Exceeding the speed limit is the theme of this issue of Signal Integrity Journal (SIJ), and nowhere is speed more of a design concern than for connectors. As connectors get smaller and denser while handling faster speeds, there is a significant chance that signal interference and crosstalk will increase. The following is a compilation of everyone’s thoughts on what’s new, what’s real, and what we should be worried about.

We want to follow this mantra of 85 ohms for PCIe, but it may not be so easy. Here’s a look at exactly what the spec says, and what we can do about it.

When is it appropriate to have a continuous plane, split planes, or no planes under an RJ45 connector? This article from Zachariah Peterson takes a closer look.

Routing 112 Gbps PAM4 signals through a system poses many challenges for designers. In this piece, SI expert Scott McMorrow explains what causes signal degradation and offers a path forward.

What are the greatest technical challenges facing connector designs for future high-speed deployments?Jairo Guerrero of Molex delves into the technical challenges for today’s connectors, the influence of applications such as automotive and data/telecom, and he gives an intriguing glimpse into the product development process at Molex.

A particularly challenging configuration is the edge launch, where connectors are used on the edge of the PCB with a transition to a microstrip trace. A poorly optimized connector footprint leads to degradation of the signal integrity performance, especially at high data rates. This paper identifies the root cause of the problem by showing how the electromagnetic fields behave at the transition area. Then it presents a design methodology, using simulated and measured data, that ensures the quality of high-speed data transmission.

If you are working on chip and package design, ground bounce is an important concern.  SIJ Technical Editor Eric Bogatin and his University of Colorado students share the results of a study in best design practices to minimize ground bounce noise.
