[Data Center Accelerator Card] Virtex UltraScale+ Series FPGA XCVU3P+ 100G Data Center Processing Accelerator Card

• 4x 100G QSFP28 Optical Fiber Channels
• PCIe x16 Host Interface, supporting XDMA and Scatter-Gather DMA
• Optical fiber channels support Aurora and other protocol standards, up to 25Gbps/lane
• 2 independent sets of DDR4 SDRAM memory, operating at 1200MHz clock frequency
• Multiple digital discrete I/O interfaces
• High-performance clock management unit

This 4-channel QSFP28 100G optical fiber channel adapter, based on a PCIe bus architecture, features one PCIe Gen3x16 host interface and a total of four QSFP28 100G optical fiber interfaces. It enables real-time data acquisition, real-time buffering, and high-speed PCIe transmission for four QSFP28 100G optical fiber channels. The board utilizes Xilinx's high-performance Virtex UltraScale+ series FPGA XCVU3P as its main processor and includes two independent 80-bit DDR4 SDRAM large-capacity data buffers. The board also has one RJ45 Gigabit Ethernet port and several I/O control signals. This board is a standard full-height PCIe form factor, widely applicable in server-based optical fiber channel data acquisition, data transmission, and similar scenarios.
