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.
