Determine the level of undesirable coupled energy between traces based on trace spacing and substrate height.

This online electrical calculator helps you determine the microstrip crosstalk on a Printed Circuit Board (PCB) based on the trace spacing and substrate height. Crosstalk refers to the undesirable coupled energy between traces, and it can be categorized as forward or retrograde.

    CTdb = 20\log_{10}\left(\frac{1}{1+\left(\frac{S}{H}\right)^2}\right)

    Where,

    • CTdb = CrossTalk
    • S = Trace Spacing
    • H = Substrate Height
