5.11.2 MII Transmit Signal Timing (FEC_TXD[3:0], FEC_TXEN,
FEC_TXER, FEC_TXCLK)
Table 17
lists MII transmit channel timings.
The transmitter functions correctly up to a FEC_TXCLK maximum frequency of 25 MHz +1%. There is
no minimum frequency requirement. In addition, the processor clock frequency must exceed twice the
FEC_TXCLK frequency.
The transmit outputs (FEC_TXD[3:0], FEC_TXEN, FEC_TXER) can be programmed to transition from
either the rising or falling edge of FEC_TXCLK, and the timing is the same in either case. This options
allows the use of non-compliant MII PHYs.
Refer to the Ethernet chapter for details of this option and how to enable it.
