Fast Ethernet AC Timing Specifications
MII signals use TTL signal levels compatible with devices operating at 5.0 V or 3.3 V.
5.15.1
MII Receive Signal Timing
The receiver functions correctly up to a FEC_RXCLK maximum frequency of 25 MHz +1%. The processor clock frequency
must exceed twice the FEC_RXCLK frequency.
Table 23 lists MII receive channel timings.
Figure 23 shows MII receive signal timings listed in Table 23.

5.15.2
MII Transmit Signal Timing
Table 24 lists MII transmit channel timings.
The transmitter functions correctly up to a FEC_TXCLK maximum frequency of 25 MHz +1%. The processor clock frequency
must exceed twice the FEC_TXCLK frequency.
Figure 24 shows MII transmit signal timings listed in Table 24.
