RMII Clock
In RMII mode of operation, the master input clock (MCLK) frequency should be 50 MHz ± 50
ppm, with a duty-cycle between 35% and 65% inclusive.

SMII Applications
The SMII ports provide eight low pin-count interfaces between the LXT9784
s eight PHYs and an
ASIC switch, as an alternative to the RMII interface. The SMII interface is composed of two
signals per port, a global synchronization signal, and a global reference clock.
