The InfiniBand SDR Link Layer Core is engineered to offer seamless connectivity across high-speed data networks. It operates at 125 MHz, delivering bidirectional data transfer rates of up to 10Gbits/second. This core is integrated with Xilinx Virtex2P, Virtex4FX, Virtex5, and Altera Stratix2GX FPGAs, and is available for ASIC applications as well. Constructed to perform optimally within lower-speed grade FPGAs, the core excels in maintaining data integrity in rigorous communication environments. The SDR Link Layer Core serves as the foundational element of Polybus's InfiniBand offerings, ensuring reliable data transport in computing and networking infrastructures.
