The CA91L8200B (PowerSpan II Dual) is a multi-port PCI bus switch that bridges PCI to the PowerQUICC II (MPC8260), MPC7xx, PowerPC™ 7xx, and PMC-Sierra WinPath™ processors. The integrated, non-transparent PCI-to-PCI bridge in the dual PCI PowerSpan II allows designers to reduce component count and increase overall system performance.
