Electrical characteristics
4.14.7.2
The transmitter functions correctly up to a TX_CLK maximum frequency of 25 MHz +1%. There is no minimum frequency
requirement. In addition, the system clock frequency must exceed four times the TX_CLK frequency.
The transmit outputs (TXD[3:0], TX_EN, TX_ER) can be programmed to transition from either the rising or falling edge of
TX_CLK, 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.
