Question on PCI SPEC

[Hiroki Kihara <kihara@cell.semicon.sony.co.jp>]

 Hellow.  My name is  Hiroki Kihara.  

 I work for sony co. semiconductor division.

 I have a question on PCI spec rev2.0 p95-p96 "Maximum AC 
 ratings and device protection" .

 I wonder whether the PCI ICs must be tolerable to the 11V input 
 for long time (ex. 10 years) or not.

 I understand  the meaning of the spec. 

 But,if the PCI buffer had zero output resistance, the signal 
 wouldn't be stable permanently, that is, anybody can't use s
 uch a buffer.

 So, I think we need not to assure the spec as long term(ex. 
 10 years) spec.


 PS.  Of course, I recognaize the meaning of the spec as short 
      term reliability.


 Regards, Kihara
