Descriptions of PCI2050BIPDV

The Texas Instruments PCI2050B PCI-to-PCI bridge provides a high performance connection path between two peripheral component interconnect (PCI) buses operating at a maximum bus frequency of 66-MHz. Transactions occur between masters on one and targets on another PCI bus, and the PCI2050B bridge allows bridged transactions to occur concurrently on both buses. The bridge supports burst mode transfers to maximize data throughput, and the two bus traffic paths through the bridge act independently.
