both 10M and 100M operation.
Analog References (RBIAS)
The four RBIAS inputs (RBIAS10_0, RBIAS10_1, and RBIAS100_0, RBIAS100_1) must have
external resistor connections. The inputs are sensitive to the resistor value and some
experimentation is required to select the correct values for any given layout. Resistors of 1%
tolerance are to be used. See
RMII Applications
The RMII ports provide eight low pin-count interfaces between the eight PHYs and an ASIC
switch, as an alternative to the SMII interface. The RMII interface is composed of seven signals per
port, and a global reference clock.
