Intel Stratix 10 FPGA Nallatech 520N FPGA Network Acceleration Card

Scalable compute node with optical I/O for creation of directly-coupled, dense FPGA clusters

Introducing ground-breaking single precision floating point performance of up to 10 TFLOPS, the OpenCL-programmable 520N features an Intel Stratix 10 FPGA, along with four banks of DDR4 external memory.

Four network ports enable dramatic FPGA-to-FPGA scaling independent of the PCIe bus, plus support for an array of serial I/O protocols operating up at 100/40/25/10G.

Notice: Nallatech’s PCIe compliant FPGA boards rely on the host’s cooling capabilities to stay within its acceptable operating temperature limits.

The user must make sure that the FPGA application is designed within the power limits documented by Nallatech and that sufficient cooling is provided to make sure the maximum FPGA die temperature is 15C below the maximum operating limit. Nallatech recommends that users perform a thermal characterization of their application in their system to meet these requirements.

» Cooling: Air convection
» Operating temperature: 5°C to 35°C
