The M-XGXSÃ¢ÂÂ¢module from Mentor Graphics provides the physical coding sublayer (PCS) functionality for transfer of Ethernet-based data between a 10-Gbps Ethernet media access controller (MAC) and a SerDes module. Depending on where the MXGXS is instantiated in the data path, the module will be considered a DTE M-XGXS or a PHYM-XGXS. It can support the XAUI interface for incorporation into a customerÃ¢ÂÂs own ASIC design. The M-XGXS module performs all mandatory and optional functionality described in Clause 47 of the IEEE 802.3ae specification. The module is made up of three main sub-modules (as illustrated in the diagram above) and two DDR modules necessary for XGMII traffic. There are many different possible applications for the M-XGXS, including network interface designs, Ethernet switching designs, and test equipment designs.
