2.3. PCIe Overview
The communication link between the Intel® FPGA PAC N3000-N and a local host server is through a PCIe Gen3 x16 Edge Connector. The card contains a PEX8747 PCIe switch with one upstream port (x16) on the edge connector, and four downstream ports (all x8) connected to Intel® Arria® 10 FPGA (two x8 ports) and one x8 port per Intel® Ethernet Controller XL710 device.
The Intel® FPGA PAC N3000-N supports PCIe* Gen3 speed. The PEX8747 PCIe switch links between Intel Arria10 and XL710 run at Gen3 speed, whereas the upstream port on the edge connector runs the highest speed supported by the host up to Gen3 speed.
The PCIe* edge connector SMBus is connected to the Intel® MAX® 10 BMC.
