11.3 XTAL Printed-Circuit Board (PCB) layout guidelines
Follow these guidelines for PCB layout:
Connect the crystal on the PCB as close as possible to the oscillator input and output
pins of the chip.
Take care that the load capacitors Cx1, Cx2, and Cx3 in case of third overtone crystal
use have a common ground plane.
Connect the external components to the ground plain.
To keep parasitics and the noise coupled in via the PCB as small as possible, keep
loops as small as possible.
Choose smaller values of Cx1 and Cx2 if parasitics of the PCB layout increase.
