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.
