11.2 XTAL Printed Circuit Board (PCB) layout guidelines
The crystal should be connected 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 usage have a common ground plane. The external components
must also be connected to the ground plain. Loops must be made as small as possible in
Fig 23. Oscillator modes and models: oscillation mode of operation and external crystal
model used for CX1/CX2 evaluation

components parameters) low frequency mode
