3.5.8.1
MII Receive Signal Timing (FEC_RXD[3:0], FEC_RX_DV, FEC_RX_ER,
and FEC_RX_CLK)
The receiver functions correctly up to a FEC_RX_CLK maximum frequency of 25 MHz + 1%. There is
no minimum frequency requirement. In addition, the FEC IPG clock frequency must exceed twice the
FEC_RX_CLK frequency.
Figure 17
shows the MII receive signal timings, and
Table 24
lists the timing parameters.

3.5.8.2
MII Transmit Signal Timing (FEC_TXD[3:0], FEC_TX_EN, FEC_TX_ER,
and FEC_TX_CLK)
The transmitter functions correctly up to a FEC_TX_CLK maximum frequency of 25 MHz + 1%. There
is no minimum frequency requirement. In addition, the FEC IPG clock frequency must exceed twice the
FEC_TX_CLK frequency.
Figure 18
shows the MII transmit signal timings, and
Table 25
lists the timing parameters.
