The MII to RMII LogiCORE is a "shim" core which converts a traditional 16-pin Media Independent Interface (MII) on a Xilinx 10/100 Ethernet MAC core to a a 6-pin Reduced Media Independent Interface (RMII) interface, allowing the MAC to connect to RMII compliant PHYs. A fixed 50 MHz reference clock synchronizes the MII_to_RMII with both interfaces.

关键特性
