Differential Pair Routing: Impedance, Spacing, Skew and EMI

Altium · Talk · YouTube title: What your Differential Pairs Wish You Knew with Rick Hartley - AltiumLive Keynote
Why it's here

HN engineers cite Hartley as the intuitive, field-based alternative to cargo-cult PCB advice, especially on differential pair routing, reference planes and EMI.

What it covers

Rick Hartley's AltiumLive keynote on differential pairs in PC boards. He argues the rules from cables and twisted pairs do not carry over, and covers which pair geometry gives the best impedance control, the right spacing, routing practice and how much skew is acceptable.
