FEC AC Timing Parameters
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, refer to the
i.MX51 Multimedia Applications Processor Reference Manual (MCIMX51RM).
This section describes the AC timing specifications of the FEC.
4.7.4.1
MII Receive Signal Timing
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. Table 70 lists the MII receive channel signal timing
parameters and Figure 42 shows MII receive signal timings.

1 In low speed mode, card clock must be lower than 400 kHz, voltage ranges from 2.7 to 3.6 V.
2 In normal speed mode for SD/SDIO card, clock frequency can be any value between 0–25 MHz. In high-speed mode, clock
frequency can be any value between 0
–50 MHz.
3 In normal speed mode for MMC card, clock frequency can be any value between 0–20 MHz. In high-speed mode, clock
frequency can be any value between 0
–52 MHz.
4 Measurement taken with CLoad = 20 pF
5 To satisfy hold timing, the delay difference between clock input and cmd/data input must not exceed 2 ns.
