Note 22-1:
Schematic design notice of "22_POWER_MT6357-IF"
Please implement 2520 & 2016 Size TMS PCB co-layout.
Please refer to MT6762_MT6357 Co-Clock Design Notice for co-layout guide
Note 22-2:
1. Please Connect P1 and R1 ball first and then to GND
2. Please Connect P2 and N2 ball first and then to GND
3. Please connect DCXO GND to main GND by independent L1-2 GND via.;
DO NOT connect it through L1 GND
