Hi All, Why is it required to provide series termination on the DDR signals (SSTL logic) on the motherboard when the DDR DIMMs themselves have series termination on every signal (as the SSTL spec states) ? I think we can get reliable signal quality without these series terminaters on the motherboard. Correct me if i am wrong. Thanks in advance for all the valuable ideas. Regards, Anand. ------------------------------------------------------------------ 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 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
