PCI2050B PCI 至 PCI 桥接器

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 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.

The PCI2050B bridge is compliant with the PCI Local Bus Specification, and can be used to overcome the electrical loading limits of 10 devices per PCI bus and one PCI device per extension slot by creating hierarchical buses. The PCI2050B provides two-tier internal arbitration for up to nine secondary bus masters and may be implemented with an external bus arbiter
