PCI Express (PCIe)

PCIe is a point-to-point serial differential low-voltage interconnect supporting up to four channels. Each lane consists of two pairs of differential signals: a transmit pair, TXP/TXN, and receive pair, RXP/RXN. The following figure illustrates the connectivity between the SmartFusion2/IGLOO2 SerDes interface and the PCIe edge connector.
