Hi experts, I am doing PCB design to communicate IC1 to IC2. The termination of these ICs: IC1 buffer: 25 ohm IC2 buffer: 50 ohm If I use a 50 ohm trace, there will be impedance mismatch and reflection at IC1 or vice versa. How should I design PCB to cater for these different terminated impedance ICs?=20 Thanks Dom ------------------------------------------------------------------ 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
