Reduced Media Independent Interface (RMII)
Overview
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.
Key Features
- 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)
