GBE0_CTREF A14 Reference voltage for Carrier Board Ethernet channel 1 and 2
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 250 mA or less. GND min
