Gigabit Ethernet Pin # Description
GBE0_CTREF
A14
Note
The GBE0_LINK# output is only active during a 100Mbit or 1Gbit connection, it is not active during a 10Mbit connection. This is a limitation
of Ethernet controller since it only has 3 LED outputs, ACT#, LINK100# and LINK1000#. The GBE0_LINK# signal is a logic AND of the
GBE0_LINK100# and GBE0_LINK1000# signals on the conga-TC87 module.

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.
