Fast Ethernet Controller (FEC) AC Electrical Specifications
This section describes the electrical information of the FEC module. The FEC is designed to support both
10- and 100-Mbps Ethernet networks. An external transceiver interface and transceiver function are
required to complete the interface to the media. The FEC supports the 10/100 Mbps Media Independent
Interface (MII) using a total of 18 pins. The 10-Mbps 7-wire interface that is restricted to a 10-Mbps data
rate uses seven of the MII pins for connection to an external Ethernet transceiver.
4.9.8.1
FEC AC Timing
This section describes the AC timing specifications of the FEC. The MII signals are compatible with
transceivers operating at a voltage of 3.3 V.
4.9.8.2
MII Receive Signal Timing
The MII receive timing signals consist of FEC_RXD[3:0], FEC_RX_DV, FEC_RX_ER, and
FEC_RX_CLK. The receiver functions correctly up to a FEC_RX_CLK maximum frequency of
25 MHz + 1%. There is no minimum frequency requirement. Additionally, the processor clock frequency
must exceed twice the FEC_RX_CLK frequency. Table 48 lists MII receive channel timings.
1 FEC_RX_DV, FEC_RX_CLK, and FEC_RXD0 have the same timing when in 10 Mbps 7-wire interface mode.
Figure 39 shows the MII receive signal timings listed in Table 48.
