GBE0_ACT# B2 Gigabit Ethernet Controller 0 activity indicator, active low. OD
GBE0_LINK# A8 Gigabit Ethernet Controller 0 link indicator, active low. O 3.3VSB
GBE0_LINK100# A4 Gigabit Ethernet Controller 0 100Mbit/sec link indicator, active low. OD
GBE0_LINK1000# A5 Gigabit Ethernet Controller 0 1000Mbit/sec link indicator, active low. OD
GBE0_CTREF A14 Reference voltage for Carrier Board Ethernet channel 0 magnetics center tap. The reference voltage is
determined by the requirements of the module PHY and may be as low as 0V and as high as 3.3V. The
reference voltage output shall be current limited on the module. In the case in which the reference is shorted
to ground, the current shall be limited to 250mA or less.
REF Not connected
