Devices with different interface voltages on BF518 EBIU

Hi everyone,

 

The EBIU of BF518 DSP currently has SDRAM and Flash memory ICs connected to it.  Both are running at 1.8V. 

 

Now, I need to add an Ethernet IC to the EBIU, but unfortunately, this Ethernet IC can only run on 3.3V.  Besides the level translation IC, do I need any buffer IC?  Is there anything else that I will need?

 

Thank you in advance!
