Hi, all. I have question about IBIS Model of the CMOS PECL. It is different from standard IBIS Model. So I difficult to make IBIS Model. ___ ___ VDD=1.8V It has termination resist of 50ohm | | and differential input of 1.3V~1.8V. /_ 50ohm /_ 50ohm It's output range is 1V ~ 1.5V. /--->out+ /- -> out - _| |_ -|_ _||- |_________| | \ 20mA | / gnd ------------------------------------------------------------------ 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
