I am connecting the i.MX6UL device with an FPGA through an RMII interface. Since this is a high speed transmission line which needs a series termination resistor. I assume maximum drive strength has typ impedance value is 23Ohm based on the datasheet, and it would need a 30Ohm resistor in series to die out the reflected voltage at load. Any recommendation for this topic?
