MII to RGMII converter

Hello, 

 

I have a EMAC from Flexibilis which can operate at 10/100 Mbps. We have configured this MAC to operate at 100Mbps. This MAC is compatible with MII interface(4 SDR data pins). We have an ethernet PHY which is compatible with RGMII interface(4 DDR data pins) which can operate at 10/100/1000 Mbps. Are there any converters available to convert the signals from MII to RGMII and vice versa?

My guess is that there aren't. Generally you match the MAC and PHY interface styles to ensure compatibility. Someone better at Verilog/VHDL than I am might advise you on how hard it would be to implement

Hi, 

 

Is this what you need? https://documentation.altera.com/#/00081203-NT$NT00080794 

 

The GMII to RGMII converter, that is one of Altera embedded peripheral Cores, can be found only in Qsys.
