Differential pair routing is a critical issue in PCB design. If the differential pair signal is high speed signal like USB 2.0, USB 3.0 or HDMI then PCB routing is harder than lower speed signals like RS485, CAN or similar. In this tutorial you are… Read More »Differential Pair Routing in Altium Designer
