Hello all, I am designing a high speed board. The signal rate between two components is 622Mbps, according to the datasheet, i have to use microstrip lines whose characteristic impedance is 50Omh. If i put the two components very close and connect the signal line as short as possible, can i avoid using microstrip lines? i think this frequency is not so high that microstirp lines have to be used. Can any one give any comments and ideas? Thank you a lot! --=20 Best Regards, Ray Jiang ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List FAQ wiki page is located at: http://si-list.org/wiki/wiki.pl?Si-List_FAQ List technical documents are available at: http://www.si-list.org 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
