DP83867IR: RGMII interface with 1.5V voltage level

Part Number: DP83867IR

Hi

I need to connect an DP83867 to an FPGA IO bank that is powered with 1.5V. What level translation circuit do you recommend? Or can I connect the RGMII interface directly?

Thanks for your help

    Hi Reto,

    We can power the VDDIO and RGMII lines using 1.8V. For using 1.5V you need to use a level shifter, please make sure it can meet the RGMII frequency.

    Do you already have a level shifter used in previous designs ?
