Place 10uF and Bead near the ASIC. The high frequency
caps on page 7 should be placed directly across
ADC0_AVDD and AVSS pins.

Adjustable for initial bringup. In the long run they will be replaced by fixed 2.5V
regulator. In that case R1 is remove and R2 is replaced with a 0 Ohm resistor.
Adjustable for initial bringup. In the long run they will be replaced by fixed 1.8V
regulators. In that case R1 is remove and R2 is replaced with a 0 Ohm resistor.
