GB_LAN
Reference voltage for carrier board Ethernet channel 0 magnetics center tap.
The reference voltage is determined by the requirements of the module's PHY and may be as low as 0V and as high as 3.3V.
The reference voltage output should be current limited on the module. In a case in which the reference is shorted to ground, the current must be limited to 250mA
or less.
