PEX8311-AA66BC Product Details

The bridge offers PCI Express™ (PCIe) bridging capability from a Generic  Local Bus to PCIe enabling users to add scalable high bandwidth  interconnection to a wide variety of applications including communication  line cards, surveillance systems, video capture cards, industrial control, office automation, IP Media Servers, RAID systems and medical imaging. Many embedded system designs utilizing PCI today can easily migrate to PCIe. The ExpressLane™ PEX 8311 bridge can be used in Root Complex mode with the device directly interfacing multiple local bus devices including processors and FPGAs to a downstream PCIe port. The bridge can also function in an EndPoint type application connecting multiple local bus components to an upstream PCIe port.

The number and variety of PCI Express native-mode devices is growing quickly. As these devices become mainstream, it will be necessary to create multifunction and multi-port adapter cards with PCI Express capability. 
The PEX 8311 can be used to create a communications line card that bridges a local processing device and memory to an upstream PCIe port. The bridge allows a line card to be a backplane or a motherboard. Figure 3 shows the PEX 8311 in this application. In this mode, the bridge acts in an “EndPoint mode”. Configuration to the bridge comes from the PCIe. Use of DMA for data path and higher priority simultaneous Direct Master/Slave for control path data is invaluable.
