Re: PCI through cable ....!!!!!!!!!!!!!!!!

[Ranjan Natarajan <ranjan@plxtech.com>]

The PLX GigaBridge Switched-PCI
Controller (GBP) is a scalable, highly available PCI
controller where a minimum of two GBPs inter-operate to form a switched
PCI network of "any-to-any" PCI bus segments. The distance
between two GBP devices can be up to fifteen feet.  The GBP's can
either be connected through cables or by traces on a PCB. The
Switched-PCI Controller is 100% compatible to leading PCI specification
including the PCI Local Bus Specification Rev 2.2 and CompactPCI Rev 2.1
(PICMG 2.0) Specification. We have done signal intergrity tests and have
working in our lab a 20 GBP ring connected through cables.  If you
would like to see a picture of how it looks or if you need a power point
presentation - please send me an e-mail.  For more
