2.1.13. Gigabit Ethernet Controller (10/100/1000Mbps) Interface
The
SMARC-FiMX6
module
supports
one
Gigabit
Ethernet
(10/100/1000Mbps) interfaces. The Gigabit Ethernet controller interfaces are
accomplished by using the low-power Qualcomm Atheros AR8035 physical
layer (PHY) transceiver with variable I/O voltage that is compliant with the
IEEE 802.3-2005 standards. The AR8035 supports communication with an
Ethernet MAC via a standard RGMII interface.
The Ethernet interface consists of 4 pairs of low voltage differential pair
signals designated from
GBE0_MDI0±
to
GBE0_MDI3±
plus control signals
for link activity indicators. These signals can be used to connect to a
10/100/1000 BaseT RJ45 connector with integrated or external isolation
magnetics on the carrier board.
