112 Gbps PAM4 Silicon and Connector Evaluation Platform

The continued progression to higher data rates puts increasing demands on the design of practical SerDes channels. At 112G-PAM4, the UI is only 17.86 ps, and signal transmission in the PCB must be highly optimized for loss, reflections, crosstalk, and power integrity. This article summarizes the key elements of a study that describes the signal-integrity and power-integrity design process and shows simulated SI and PI performance correlated to measured data as well as measured eye diagrams of a test board that uses a 112G-capable silicon and high-speed compression-mount cable connectors.

Current Distribution, Resistance, and Inductance in Power Connectors

Engineers who design and model power distribution networks require accurate component level models from high frequency down to DC.  Accurate modelling of power connectors can guarantee best power transfer and minimize power-induced noise.  In this paper, which won a DesignCon 2020 Best Paper Award, the authors analyze the frequency-dependent resistance and inductance of various power connectors as well as pin patterns.

The Truth About High-Speed Connector Design

It’s Not as Simple as Just Putting Metal and Plastic Together

In the high-speed connector design arena, there are two opposing ideas. For some people, if you simply put pieces of plastic and metal together, eventually you have a signal transmission. This process is very simple. On the other end of the spectrum, there is the idea that a solid connector design requires a deep understanding of electromagnetic theory, a wisdom only sorcerers and wizards possess.
