David, I recall this device from my days of working on Fibre Channel=2E The Fibre Channel Tx and Rx on the QLogic ISPs are Gigablaze, which is an LSI Logic family of high speed serdes=2E The Gigablaze 1998 version was most likely LVPECL, and SPICE models should be available, you probably need to contact LSI Logic=2E Good luck, Fabrizio Zanella -----Original Message----- From: haedge@raytheon=2Ecom [mailto:haedge@raytheon=2Ecom] Sent: Tuesday, January 23, 2007 5:35 PM To: si-list@freelists=2Eorg Subject: [SI-LIST] QLogic ISP2100 Does anybody out there in the SI world have any information on either a QLogic ISP2100, ISP2100A or ISP2200? I am interested mainly in the Fibre Channel parts of the chip=2E Specifically , is the drive CML, PECL or what? Are there any SPICE models that exist for the drivers? If not, has anybody used any company that can generate SPICE models from actual parts? Is there any documentation that describes how to change output voltage swing, bias, output impedance, etc=2E on the drivers? I also know that the IP for the drivers is from LSI=2E The press release in 1998 from QLogic states that is known as LSI "Gigablaze" technology, if that rings a bell with anybody=2E Any info on these devices would be much appreciated=2E Internet searches and company inquires have yielded next to nothing on these parts=2E David Haedge Raytheon Company ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@freelists=2Eorg with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: http://www=2Efreelists=2Eorg/webpage/si-list For help: si-list-request@freelists=2Eorg with 'help' in the Subject field List technical documents are available at: http://www=2Esi-list=2Enet List archives are viewable at: http://www=2Efreelists=2Eorg/archives/si-list or at our remote archives: http://groups=2Eyahoo=2Ecom/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www=2Eqsl=2Enet/wb6tpu ------------------------------------------------------------------ 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 technical documents are available at: http://www.si-list.net 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
