60.6.2 Crystal Oscillator

Figure 60-9. 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 60-4. Crystal Oscillator Checklist
Signal Name	Recommended Pin Connection	Description
XIN	Load capacitor 26pF⁽¹⁾⁽²⁾	External crystal between 8 to 48MHz
XOUT	Load capacitor 26pF⁽¹⁾⁽²⁾	External crystal between 8 to 48MHz

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.
