53.7.2 Crystal Oscillator

The crystal oscillator schematic is shown below:

Figure 53-8. Crystal Oscillator Schematic

The crystal must be located as close to the device as possible. Long-signal lines may cause too high of a load to operate the crystal, and cause crosstalk to other parts of the system.

Table 53-5. Crystal Oscillator Checklist
Signal Name	Recommended Pin Connection	Description
XIN	Load capacitor. Value depends on Crystal manufacturers recommendation.⁽¹⁾	External crystal between 0.4 to 32 MHz
XOUT	Load capacitor. Value depends on Crystal manufacturers recommendation.⁽¹⁾	External crystal between 0.4 to 32 MHz

Note:

The capacitors must be placed close to the device for each supply pin pair in the signal group.
