Functional Block Diagram

A 4-channel QSFP28 100G Fibre Channel adapter based on a PCIe bus architecture. The card features one PCIe Gen3x16 host interface and a total of four QSFP28 100G fiber interfaces, enabling real-time data acquisition, real-time buffering, and high-speed PCIe transmission for four QSFP28 100G fiber channels. The card uses Xilinx's high-performance Virtex UltraScale+ series FPGA XCVU3P as the main processor, with two independent sets of 80-bit DDR4 SDRAM for large-capacity data buffering. The card also includes one RJ45 Gigabit Ethernet port and several I/O control signals. This standard full-height PCIe card can be widely applied in server-based Fibre Channel data acquisition, data transmission, and other scenarios.
