FEC Electrical Characteristics
13 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 V or
3.3 V.
13.1
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 29 provides information on the MII receive signal timing.
Figure 72 shows MII receive signal timing.
