Lots of interesting papers were presented at DesignCon 2015 (which is the conference for signal-integrity), all about going up in speed breaking the 32 Gbps barrier and more.
I picked one to show you here because it relates directly to a brand new course we ran in Stockholm in May 2015. It’s a one-day course by Lee Ritchey focused on how to design very fast differential data paths on printed circuit boards.
The tutorial presented at DesignCon covers both this and a lot of verification techniques using S-parameters.
The presentation is co-authored between Lee Ritchey, Heidi Barnes (Keysight) and Tim Wang Lee (Wild River). All of them are top experts in this field.
This paper talks a lot about de-embedding the test fixtures when doing S-parameter measurements. We have previously arranged full courses on S-parameters with Eric Bogatin and will always recommend his courses for this subject.
Another important aspect of high-speed links is the exact dimensions for the high-speed vias used in the transmission lines used to form the links. Feel free to use the ones I present in the article linked.
Enjoy reading, and seriously consider signing up for one of our courses now or in the future.
