The InfiniBand QDR Link Layer Core is tailored for extreme data environments, operating at up to 500 MHz in ASICs and 250 MHz in FPGAs. It supports multiple data rates, including 1X, 4X, and 8X QDR operation, facilitating versatility in deployment. Suitable for both Xilinx and Altera platforms, the core is integral to systems requiring fast, efficient data handling capabilities. With an embedded PCS Layer, this core also accommodates high-speed SerDes interfaces, crucial for maintaining low-latency and high-throughput data processes in demanding networking systems.
