Karl and Corey talk about some of the lessons Karl learned (and remembered) at the Signal Integrity Boot Camp at DesignCon.
Part of the Podcast
STM32F0 - They are microcontrollers. Enough said.
U2043b - Turn signal flasher
Be The Signal Slides
Here are the slides I was referring to: http://www.bethesignal.com/bogatin/practical-sparameter-measurement-analysis-p-1076.html

The same points can be made but using the fact that the dielectrics are different.
I.E. same loss but different speeds = still not good.
