Ethernet Port

The OEM638 provides a 10/100 Ethernet port with auto-negotiation. The Ethernet interface is not
enabled by default and may require configuration (refer to details that follow and consult the
Family Firmware Reference
and the SAVEETHERNETDATA
PHY terminations are provided on the OEM638 card and a 3.3 V output is presented to bias the Ethernet
magnetics. This 3.3 V bias output from the OEM638 card is not to be used for any purpose other than
biasing the Ethernet magnetics.
A reference schematic is shown below.
