Ethernet Interface
Connection of the phyCARD-M to the world wide web or a local area
network (LAN) is possible using the integrated FEC (Fast Ethernet
Controller) of the i.MX35. The FEC operates with a data transmission
speed of 10 or 100 Mbit/s.
9.4.1
PHY Physical Layer Transceiver (U7)
With a physical layer transceiver mounted at U7 the phyCARD-M has
been designed for use in 10Base-T and 100Base-T networks. The
10/100Base-T interface with its LED signals extends to phyCARD-
Connector X2.

Location of the Ethernet signals
The Ethernet PHY provides MII/RMII/SMII interfaces to transmit and
receive data. In addition the PHY also supports HP Auto-MDIX
technology, eliminating the need for the consideration of a direct
connect LAN cable, or a cross-over patch cable. It detects the TX and
RX pins of the connected device and automatically configures the
