Fast Ethernet AC Timing Specifications
Media Independent Interface (MII) Fast Ethernet Controller (FEC) signals use transistor-to-transistor logic
(TTL) signal levels compatible with devices operating at 3.3 V. The timing specifications for the MII FEC
signals are independent of the system clock frequency (part speed designation).
3.14.1
MII FEC Receive Signal Timing
FEC_RXD[3:0], FEC_RX_DV, FEC_RX_ER, and FEC_RX_CLK
The receive functions correctly up to an FEC_RX_CLK maximum frequency of 25 MHz plus one percent.
There is no minimum frequency requirement. The processor clock frequency must exceed four times the
FEC_RX_CLK frequency.
Table 28 lists MII FEC receive channel timings.
Figure 28 shows MII FEC receive signal timings listed in Table 28.
