Hello , I'm looking at the VI curve of PCI spec rev 3.0 version. Under AC specs, I want to know how did PCI get the exact equations for Ioh and Iol for different Vout voltage range.Please suggest any study material for derivation of these. Also if these curves ( Vout Vs Idriver ) are met in DC condition, will they really meet in transient also. ? Does any of you have answer for these? I am a student and really looking for any book which can explain my this question and questions related to the PCI IO .
