Notes:
1.
The MDIO buffer is powered from the 2.5v power rail - the output signal level is 200mV below the
rail for MDIO. 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.
