    X550-AT2 VCCA pins


      The Pin Interface section of the Intel® Ethernet Controller X550 Datasheet lists VCCA pins as 1.0V power pins. Except from this, the pins are not mentioned at all in the document. The Electrical/Mechanical Specification section only describes 4 voltage rails:

      VCC3P3, VCC2P1, VCC1P2, VCC0P83. From the reference schematics it looks like these pins should only connect to decoupling capacitors and no voltage source. Is this correct? Where is it documented?
