Determining Impedance Matching Requirements in High-Speed PCB Design.
Bitu , 01-08-2025, 05:32 PM
How do we determine the required impedance matching for a signal or track in high-speed PCB design? For example, sometimes I see 90 ohms, sometimes 120 ohms, and other times 100 ohms.
I am learning PCB design. Please help me understand.
