Figure 38. MII Receive Signal Timing Diagram
4.7.5.2
MII Transmit Signal Timing
The MII transmit signal timing affects the FEC_TXD[3:0], FEC_TX_EN, FEC_TX_ER, and
FEC_TX_CLK signals. 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 processor clock frequency
must exceed twice the FEC_TX_CLK frequency.
Table 53 lists MII transmit channel timing parameters. Figure 39 shows MII transmit signal timing
diagram for the values listed in Table 53.
