12.0 Ethernet Section

The Evaluation board provides two options for Ethernet connectivity, a direct connection
through an RJ-45 jack which provides a 10/100 compatible interface capable of being
attached to an Ethernet network or the ability to directly connect to the embedded
Ethernet PHY on the Airborne Device Server module. The Ethernet circuit can be seen in
Figure 34.
The direct connection is available through CN3 (5.6) and requires J8 (5.21) to be
configured correctly. If CN3 is used the most common connection method is capacitive
coupling directly to a second PHY.
A 10/100 Ethernet PHY interface is supported when the Ethernet device type is selected
in firmware. This interface is a 10/100Mbps interface that supports auto negotiation and
cross-over cabling. The interface also supports both half and full duplex for 10Mbps and
100Mbps.
The interface uses a Broadcom BCM5241A Ethernet PHY, please refer to the
manufacturers datasheet for interface details and appropriate design guidelines for both
capacitive coupling and magnetic interface.
