FEC Electrical Characteristics
15.1 MII and Reduced MII Receive Signal Timing
The receiver functions correctly up to a MII_RX_CLK maximum frequency of 25 MHz + 1%. The reduced MII
(RMII) receiver functions correctly up to a RMII_REFCLK maximum frequency of 50 MHz + 1%. There is no
minimum frequency requirement. In addition, the processor clock frequency must exceed the MII_RX_CLK
frequency
–
1%.
Table 34
provides information on the MII and RMII receive signal timing.
Figure 72
shows MII receive signal timing.

15.2 MII and Reduced MII Transmit Signal Timing
The transmitter functions correctly up to a MII_TX_CLK maximum frequency of 25 MHz +1%. The RMII
transmitter functions correctly up to a RMII_REFCLK maximum frequency of 50 MHz +1%. There is no minimum
frequency requirement. In addition, the processor clock frequency must exceed the MII_TX_CLK frequency
–
1%.
