From the article:
> any interference affects the [diff pair] signals equally – as signals are compared to each other to receive information, this means that the information received is not affected by noise overlaid onto both of the signals.
This is not true - a common myth about differential pairs. Don't rely on it for your designs. More info - see page 15 https://www.speedingedge.com/PDF-Files/DiffSigDesign.pdf https://www.speedingedge.com/PDF-Files/DiffSigDesign.pdf
