I have a conflict it seems with regard to DP83848C RMII bus impedance. The datasheet references the IEEE spec of 68 ohms for the bus impedance, but the TI design review package I received states 50 ohms for RMII interface. Can I get a clarification on impedance specs for RMII interface (data and control) on the DP83848C I plan to use? Apologies if this topic has come up before, I could not find it.
