3.17.3.2

RMII receive signal timing (RXD[1:0], CRS_DV)

The receiver functions correctly up to a REF_CLK maximum frequency of 50 MHz +1%.

There is no minimum frequency requirement. The system clock frequency must be at least

equal to or greater than the RX_CLK frequency, which is half that of the REF_CLK frequency.
