FPGA SmartNIC FB2CDG1@AGM39D-2 Intel® based

Dual port QSFPDD56 2×400G PCIe Gen5 x16 Intel® Agilex™ M-series Based

The Silicom FB2CDG1@AGM39D-2 ThunderFjord B is a high-performance programmable PCIe Server adapter based on the Altera® Agilex™ M-series AGMF039 FPGA (option for AGMF032).

The Altera Agilex-M™ is an extremely powerful FPGA which also features up to on-chip 32GB HBMe2 memory providing an unprecedented 2 x 2.6 Tbps HBMe2 bandwidth. The combination of lightning fast logic and equally fast memory ensures a platform that can deliver

The card FB2CDG1@AGM39D-2 is equipped with 2 x QSFPDD56 for supporting 2x 400GE, as well as a wide range of other link speed combinations like 16×10/25GE or even 8x100G with the appropriate breakout modules.

The FB2CDG1@AGM39D-2 ThunderFjord features 2 x AcceleRate® Slim Cable Assembly (ARC6) connectors with 2x 8x28Gbps from Samtec. The ARC6 connectors add unprecedented flexibility in host bandwidth and network connectivity. Silicom offers an adaptor an additional PCIe Gen4 x16 connector that can be employed for additional host bandwidth. The same connectors can alternatively be used with Fireflytm flyover cables for connecting additional 2x 8xFSFP28 or 2x 2xFQSFP28 for higher Ethernet link capacity to the solution in appliances. Silicom offers a 4xFQSFP28 bracket for easy utilization of the expansion option. The AR6-16 can alternatively be used for direct connection of two boards, connect multiple cards in series or daisy chain, or connect to other products with suitable interface.

The AGM FPGA series features CXL 1.1 and 2.0, providing heterogeneous processing and computing in performance-intensive workloads like AI, machine learning and analytics. Additionally, the AGM FPGA device includes Quad-core 64 bit Arm Cortex A53 processor.
