Current increase when REFB is enabled with a
110.42 MHz reference input; combined current
delta of Pin 3 and Pin 7
Delta from bypassing reference divider to using
reference divider = 2; total feedback division

M2 divider = 3; D3 and D4 divider = 1; OUT3 and
OUT4 enabled to 800 mV; no internal termination;
associated low-dropout regulators (LDOs)
