Reduced Media Independent Interface (RMII)


Product Description

The MII to RMII LogiCORE is a "shim" core which converts a traditional 16-pin Media Independent Interface (MII) on an AMD 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.

Key Features and Benefits

  • Option to specify fixed 10 or 100 Mbit per second throughput
  •  Automatic detection of Receive side throughput 
  • Fixed clock frequency of 50 MHz Designed to RMII Consortium specification 
  • Free core provided with the Embedded Development Kit (EDK)
