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

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.
1. AVSS18_AUD is connected to GND with
very short trace
2. AVSS18_AUD is connected to de-couple
cap of AVDD18_AUD and AU_V18N with 6mil
trace respectively
