DESCRIPTION
The PI7C21P100B is a 2-port PCI-X 2.0 Bridge designed to be compliant with the PCI-X
Addendum to the Local Bus Specification Revision 1.0a. The PI7C21P100B is able to handle
64-bit data at a maximum bus frequency of 133MHz. The PI7C21P100B is designed for high
speed applications such as Ethernet, SCSI, and Fibre Channel. The PI7C21P100B may also
be used for bus expansion, frequency isolations/translations, or PCI-X to PCI
isolations/translations.
