Electrical Characteristics
4.7.5
This section describes the electrical information of the Fast Ethernet Controller (FEC) module. The FEC
is designed to support both 10 and 100 Mbps Ethernet/IEEE 802.3 networks. An external transceiver
interface and transceiver function are required to complete the interface to the media. The FEC supports
the 10/100 Mbps MII (18 pins in total) and the 10 Mbps (only 7-wire interface, which uses 7 of the MII
pins), for connection to an external Ethernet transceiver. For the pin list of MII and 7-wire, see the i.MX53
Reference Manual.
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.
4.7.5.1
The MII receive signal timing involves the FEC_RXD[3:0], FEC_RX_DV, FEC_RX_ER, and
FEC_RX_CLK signals. The receiver functions correctly up to a FEC_RX_CLK maximum frequency of
25 MHz + 1%. There is no minimum frequency requirement but the processor clock frequency must
exceed twice the FEC_RX_CLK frequency.

.
FEC_RX_DV, FEC_RX_CLK, and FEC_RXD0 have same timing in 10 Mbps 7-wire interface mode.
Test conditions: 25pF on each output signal.
