33.13 Fast Ethernet AC Timing Specifications
MII signals use TTL signal levels compatible with devices operating at either 5.0 V or 3.3 V.
33.13.1 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%. There is no
minimum frequency requirement. In addition, the processor clock frequency must exceed twice the
ERXCLK frequency.

Note: Output numbers depend on the value programmed into the IFDR; an IFDR programmed
with the maximum frequency (IFDR = 0x20) results in minimum output timings as shown in

values programmed into the IFDR; however, the numbers given in
values.
Because SCL and SDA are open-collector-type outputs, which the processor can only actively
drive low, the time SCL or SDA take to reach a high level depends on external signal capacitance
and pull-up resistor values.
