 VCC and DGND layout traces should be as wide as possible. Connect a 0.1uF capacitor between each VCC

and DGND pins, as close as possible to the pins.

 It is recommended to keep the traces connecting the 3.3V power supply to VCC pins as short as possible

with wide PCB traces.

 Connect AGND to EXP with a single short trace.

 Connect PLL_GND to EXP with a single short trace.

 Connect L1, L2, C13, C3, C5, C7, C8, C11, and C12 as close as possible to their pins.

 Connect R1 as close as possible to the RXI pin.

 Connect all filtering caps as close as possible to their pins.

 Connect crystal and its capacitors close to OSCI and OSCO pins. Keep DGND plan around them.
