The QDR version of the InfiniBand Link Layer Core stands at the forefront of high-speed data processing, functioning at 500 MHz in ASIC environments and 250 MHz in FPGA implementations. It supports both 1X and 4X QDR operations, with the capacity for 8X DDR operations in FPGAs. The inclusion of a robust PCS Layer ensures cross-compatibility with high-end FPGA systems such as Altera Stratix5GX, Xilinx Kintex7, and Virtex7. The QDR Link Layer Core is engineered to manage substantial data flows, empowering industries such as data acquisition and telecommunications to achieve optimum throughput in their operations.
