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 250 mA or less.
