Fast Ethernet AC Timing Specifications
MII signals use TTL signal levels compatible with devices operating at either 5.0 V or 3.3 V.
7.10.1
MII Receive Signal Timing (ERXD[3:0], ERXDV, ERXER, and
ERXCLK)
The receiver functions correctly up to a ERXCLK maximum frequency of 25 MHz +1%. The processor
clock frequency must exceed twice the ERXCLK frequency.
Table 18 lists MII receive channel timings.
Figure 19 shows MII receive signal timings listed in Table 18.
