Crystal Connectivity to the 82567
The current from the 82567 does not change regardless of generating the 1.05 V using
the on-die transistor or an external pass transistor. The total current demand remains
constant, but the power dissipated by the 82567 package changes. The 1.05 V power is
either on-die or at the external pass transistor.
