DP83848J: Level translator for MII interface for microcontroller @1.8V

Abhishek

Part Number: DP83848J

Hi,

DP83848J recommended voltage is 3.3V and the microcontroller works at 1.8V. Is it good to use a level translator in the MII interface? Any level translator part recommendation from TI.

Thank you,

Abhi
