You'll have to simulate this one. When you're not doing point-to-point on 133MHz PCIX, I have never found a formula. You may have to play with topologies and line length constraints and balance them against your physical constraints of the board, but provided you are in a closed system (no PCI connector cards), simulation should yield a solution. =20 -Chris >-----Original Message----- >From: si-list-bounce@xxxxxxxxxxxxx [mailto:si-list-bounce@xxxxxxxxxxxxx] On >Behalf Of Babid A >Sent: Wednesday, May 31, 2006 2:16 PM >To: si-list@xxxxxxxxxxxxx >Subject: [SI-LIST] PCI-X (133Mhz) bus terminations > >Hello, > > I have PCI-X bus(133Mhz) driver with a fan out of 2.
