Close to MT6577
External LNA should be located near Antenna
2. L2(AVDD55_SMPS) & K2(GND_SMPS) Line shoud be more than 0.2 width
1. GND_SMPS, which is DC-DC power ground should be directly connected
to battery ground, instead of sharing ground with main GND
3. Make star connection for AVDD13 (Both E6,E7 and E4,C4,G1)
Keep ther FM_RX_IN_N and FM_ANT in
differential trace to connect to audio jack
2. GND clearance over 1.5mm surrounding TCXO
3. GND clearance over 2mm direction to MT6620 side
4. Spacing between TCXO and MT6620 over 2mms as possible.
