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.
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) |
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.
