In any case, the base concept is still the same - I don't think that your SFP module understands that it's communicating with a USXGMII core on the MAC side, which is why it's failing to complete AN and failing to get a link established. Modules I. XGMII 10 Gbit/s 32 Bit 74 156. A cross link multiplexer bus comprising a plurality of cross link multiplexers and a plurality of interconnects. 25 Gbps) implementations on Stratix IV (GX and GT) FPGAs. • XAUI Extender: This block is an XGMII extender to support the XAUI protocol through a FPGA IP MAC core in the FPGA fabric. It achieves 10Gbps line-rate and has two interfaces with two different clock domains.
