Route AVDD18_AUXADC/AUXADC_VIN as differential trace (3 mil each)with well GND shielding
and route AVSS18_AUXADC with 15mil trace width under
AVDD18_AUXADC/AUXADC_VIN trace to provide return current path.
P1 and R1 ball connect firstly
Please connect DCXO GND to main
GND by independent L1-2 GND via.
DON'T connect it through L1 GND
P2 and N2 ball connect firstly
