![]() While you can work out many of these details by hand or with a circuit design program to model impedance in your board, the best PCB design tools give you more sophisticated ways to design for controlled impedance. Impedance in your traces becomes a critical parameter to consider during stackup design for high-speed PCBs, but the stackup will also influence crosstalk susceptibility and sheet capacitance between ground and power planes. ![]() ![]() High-speed designs carry a requirement for controlled impedance, crosstalk control, and the need for interplane capacitance. There are many demands placed on PCB stackup design. ![]()
