3.5.6 Ethernet Port
OEM7 receivers, except the OEM719, provide a 10/100 Ethernet port with auto-negotiation. The
Ethernet interface is disabled by default and must be configured. See the OEM7 Installation and
Operation User Manual (OM-20000168) for instructions on Ethernet device configuration. The
PHY layer is based on the Micrel KSZ8851 Ethernet controller.
PHY terminations are provided on the OEM7 receiver card and a 3.3 V output is presented to bias
the Ethernet magnetics. The 3.3 V power supplied by the OEM7 receiver card is not to be used
for any purposes other than biasing the Ethernet magnetics.
A reference schematic is shown in Figure 9: Ethernet Reference Schematic on the next page.
The ferrite bead is included as an EMI de-risk contingency and may not be necessary.
