(I could not read my hand writing :) Hi all: I am really interested in knowing if there are rules in wiring High speed differential clocks. We wire them parallel about 5-10mil apart and they should have the same length (wired in the inner layer) I learned in one of the classes that it is wired that way for ' convenience' and it is not necessary that they are wired parallel and close to each other. I have to convince other people and myself with that and I need more data. Thanks for your help Bouchra ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
