Hello all, I am looking for a method to determine the minimum distance which I can route 1 GHz traces from other devices (including metal pin row headers) without compromising the EMC performance (characteristic impedance) of the traces, while preventing any common-mode coupling to the other devices.
Any formulas, suggestions, or ideas are appreciated. Also, if anyone knows of any EMC layout modelling software which addresses this issue, please let me know. Thank you, Randall T. Flinders Emulex Corporation [email protected]
