Where you put the phase delay bumps on a differential pair is not a preference. It changes your EMI, your common mode noise, and whether your signals arrive intact at the receiver. This video covers t

Differential pairs don't need a return plane. You may have heard that before. It's wrong. This video proves it with simulation. Using the SATA 100Ω differential pair from the previous video, we run th

A single trace cannot survive in the noise world above a certain speed. So engineers built something that can. Every high-speed interface on a modern PCB runs as a differential pair: USB, PCIe, HDMI,

Knowing your differential pair should be 100 ohms is one thing. Verifying it actually is before the board goes to fab is another. This video walks through the complete workflow in Allegro X for differ

Same stack up. Same length matching. Same impedance targets. Different routing path and a completely different eye diagram. This video proves why routing decisions on high-speed differential pairs lik

Best practices and stack-up recommendations will get you close but they won't tell you whether your differential pairs actually pass at the data rate you're targeting. The only way to know before the

Two traces routed too close together share more than space, they share energy. That electromagnetic coupling is crosstalk, and it doesn't take much to cause bit errors, signal distortion, and chips re

"How many vias do you need?" It depends, but crossing your fingers and adding more hoping for the best isn't an answer. IR drop is a geometry problem, and the only reliable way to solve it is to simul
