14 FEC Electrical Characteristics
This section provides the AC electrical specifications for the fast Ethernet controller (FEC). Note that the timing
specifications for the MII signals are independent of system clock frequency (part speed designation). Also, MII
signals use TTL signal levels compatible with devices operating at either 5.0 or 3.3 V.
14.1 MII Receive Signal Timing (MII_RXD [3:0], MII_RX_DV,
MII_RX_ER, MII_RX_CLK)
The receiver functions correctly up to a MII_RX_CLK maximum frequency of 25 MHz + 1%. There is no minimum
frequency requirement. In addition, the processor clock frequency must exceed the MII_RX_CLK frequency – 1%.
Table 33 shows the timings for MII receive signal.
Figure 74 shows the timings for MII receive signal.
