Overview of two-way QSFP+ Optical Fiber PCIe Card and Board based on kintex UltraScale XCKU040

This card is independently developed by our company, based on Xilinx UltraScale Kintex series FPGA XCKU040-FFVA1156-2muri architecture, high-speed signal processing board supporting PCIE Gen3 x8 mode, with two 40G QSFP+ interfaces, two sets of 64-bit DDR4, each set of capacity 8Gbyte, can run stably in 2400MT/s. The board has the characteristics of automatic power-up sequence, fast program loading in BPI mode, supporting two system clock access modes on / off the board, and the design meets the requirements of industrial grade. This card can be used for high-speed signal processing. The physical figure is shown in figure 1:
