Universal Serial Bus (USB) is the world’s most popular and widely used computer interface. Layout of USB designs is not complicated, but you must keep several factors in mind to preserve signal quality.

This video explains the most common layout topics for USB signals: impedance, trace length and matching, and printed circuit board (PCB) stack-up. The examples we provide focus on USB 2.0 high speed, but the lessons also apply to USB 3 Gen 1 and Gen 2.
