GBE1_LINK1000#: Ethernet controller 1Gbps link indicator. Active Low Output signal, +3.3V_ALW electrical level
GBE1_SDP: Software defined pin, directly managed by Intel® Ethernet Controller I210 for Gigabit Ethernet #1
Please refer to the following schematics as an example of connection of Ethernet interface on the carrier board, with TVS diodes specifically designed to protect
sensitive components which are connected to high-speed data and transmission lines from overvoltage caused by ESD. In this example, it is also present
GBE_CTREF signal connected on pin #2 of the RJ-
therefore the signal GBE_CTREF is not available on SMARC connector
Please notice that if just a FastEthernet (i.e. 10/100 Mbps) is needed, then only MDI0 and MDI1 differential lanes are necessary, for both Gigabit Ethernet interfaces

Watchdog
WDT_TIME_OU: Watchdog timer Output. +1.8V_DSW electrical level
