2.1.3.4 Ethernet Connectivity (X9)
Figure 25:
Ethernet Interface at Connector X9
The Ethernet interface of the phyCORE is accessible at an RJ-45 connector (X9) on the carrier board. Due to its
characteristics this interface is hard-wired and can not be configured via jumpers. The LEDs for LINK (green) and
SPEED (yellow) indication are integrated in the connector.
The required termination resistors for the Ethernet interface are assembled on the phyCORE-OMAP44xx.
The Ethernet circuit includes a protective circuit to avoid a reverse current over the terminating resistors if the
Ethernet controller's supply voltage VCC_3V3_S is turned off by the power management on the phyCORE-
OMAP44xx. Please refer to
The Ethernet interface also supports Power over Ethernet (PoE). Please refer to
information.
