1. Fillcut TCXO area including Lay 8th,7th,6th
Close to MT6620
Close to MT6620
Close to Pin A5
Close to Pin A3
Near To LNA
Optional LNA
2. GND clearance over 1.5mm surrounding TCXO
differential trace to connect to audio jack
Keep ther FM_RX_IN_N and FM_ANT in
3. Make star connection for AVDD13 (Both E6,E7 and E4,C4,G1)
to battery ground, instead of sharing ground with main GND
1. GND_SMPS, which is DC-DC power ground should be directly connected
2. L2(AVDD55_SMPS) & K2(GND_SMPS) Line shoud be more than 0.2 width
External LNA should be located near Antenna
