51.6.2 Crystal Oscillator

Figure 51-7. Crystal Oscillator Schematic

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

Table 51-5. Crystal Oscillator Checklist
Signal Name	Recommended Pin Connection	Description
XIN	Load capacitor 15 pF⁽¹⁾⁽²⁾	External crystal between 0.4 to 32 MHz
XOUT	Load capacitor 15 pF⁽¹⁾⁽²⁾	External crystal between 0.4 to 32 MHz

1. These values are only given as a typical example.

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