Use level translator for RGMII signals

hi all,

 

I want to connect 88E1111 to virtex-7, both RGMII and SGMII will be used. Since the IO level of v7 is 1.8v and 88E1111 need 2.5v, can i use a level translator such as SN74AVC16245 between them?

 

regards

Hi

 

Yes,if you are not using an 1.8 V RGMII-only PHY device and want to use 2.5V PHY you have to use  external voltage level shifting logic.
