3U VPX Xilinx Kintex UltraScale FPGA-Based Fibre-Optic I/O Module

The XPedite2570 from Extreme Engineering Solutions (X-ES) is a high-performance, reconfigurable, conduction- or air-cooled, 3U VPX, FPGA processing module based on the Xilinx Kintex UltraScale family of FPGAs.

With multiple high-speed fabric interfaces, x8 PCI Express Gen3, 12 high-speed fiber-optic transceivers, and 8 GB of DDR4-2400 SDRAM in two channels, the XPedite2570 is ideal for customisable, high-bandwidth, signal-processing applications.

The XPedite2570 is a reconfigurable FPGA resource designed to meet the demands of high-bandwidth applications such as packet processing, signal processing, and DSP-intensive applications. It features 12 rugged, protocol-independent fiber optic transceivers operating at up to 10.3125 Gb/s, along with 8 GB of DDR4 ECC SDRAM in two independent channels capable of up to 38 GB/s aggregate bandwidth.

The XPedite2570 has several options for high-performance backplane I/O, including a x8 Gen3 PCI Express interface, dual GTH transceivers with a maximum data rate of 16.375 Gb/s, and up to 44 LVDS transceivers for user I/O.

The X-ES FPGA Development Kit (FDK) is provided to support the requirements of high-performance, real-time, embedded, streaming-data applications and simplify FPGA development. X-ES’ FDK includes IP blocks, HDL, test benches, Linux drivers, and complete example designs for the XPedite2570.
