Notes:
1.
The RMII buffer is powered from the 2.5v power rail - the output signal level is
100mV below the rail for RMII. In the ideal case, the Voh equals the 2.4v in
accordance to the RMII specification. If the 2.5v power rail drops below the ideal
value the buffer will violate the RMII specification and the 0.4v margin between
Voh/Vih will be reduced under this condition.

V_OH Max = VCC25 for GbE Ports 1 and 2 or VCCSUS25 for GbE Port 0
