The Texas Instruments PCI2050B PCI-to-PCI bridge provides a high performance connection path between twoperipheral component interconnect (PCI) buses operating at a maximum bus frequency of 66-MHz. Transactionsoccur between masters on one and targets on another PCI bus, and the PCI2050B bridge allows bridged transactionsto occur concurrently on both buses. The bridge supports burst mode transfers to maximize data throughput, and thetwo 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 electricalloading limits of 10 devices per PCI bus and one PCI device per extension slot by creating hierarchical buses. ThePCI2050B provides two-tier internal arbitration for up to nine secondary bus masters and may be implemented withan external bus arbiter.The CompactPCI hot-swap extended PCI capability makes the PCI2050B bridge an ideal solution for multifunctioncompact PCI cards and adapting single function cards to hot-swap compliance.The PCI2050B bridge is compliant with the PCI-to-PCI Bridge Specification (Revision 1.1). The PCI2050B bridgeprovides compliance for PCI Bus Power Management Interface Specification (Revision 1.1). The PCI2050B bridgehas been designed to lead the industry in power conservation and data throughput. An advanced CMOS processachieves low system power consumption while operating at PCI clock rates up to 66-MHz.
