Fast Ethernet AC Timing Specifications
Figure 18 shows timing for the values in Table 51 and Table 52.

6.10 Fast Ethernet AC Timing Specifications
MII signals use TTL signal levels compatible with devices operating at either 5.0 V or 3.3 V.
6.10.1 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%. There is no
minimum frequency requirement. In addition, the processor clock frequency must exceed twice the
ERXCLK frequency.
Table 53 lists MII receive channel timings.

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 Table 52. The I2C interface is designed to scale the actual data
transition time to move it to the middle of the I2C_SCL low period. The actual position is
affected by the prescale and division values programmed into the IFDR; however, the
numbers given in Table 52 are minimum values.
2
Because I2C_SCL and I2C_SDA are open-collector-type outputs, which the processor can
only actively drive low, the time I2C_SCL or I2C_SDA take to reach a high level depends
on external signal capacitance and pull-up resistor values.
