NOTES:
1. Includes parasitic bond and package capacitance (approximately 2pF per pin).
Since the PCB adds additional capacitance it is recommended to verify the correct load by measuring the ACLK frequency. For a
correct setup the effective load capacitance should always match the specification of the used crystal.
2. Requires external capacitors at both terminals. Values are specified by crystal manufacturers.
3. Measured with logic level input frequency but also applies to operation with crystals.
4. Frequencies below the MIN specification will set the fault flag, frequencies above the MAX specification will not set the fault flag.
Frequencies in between might set the flag.
5. To improve EMI on the XT2 oscillator the following guidelines should be observed.
Keep traces as short as possible between the device and the crystal.
Design a good ground plane around the oscillator pins.
Prevent crosstalk from other clock or data lines into oscillator pins XIN and XOUT.
Avoid running PCB traces underneath or adjacent to the XIN and XOUT pins.
Use assembly materials and praxis to avoid any parasitic load on the oscillator XIN and XOUT pins.
If conformal coating is used, ensure that it does not induce capacitive/resistive leakage between the oscillator pins.
Do not route the XOUT line to the JTAG header to support the serial programming adapter as shown in other
documentation. This signal is no longer required for the serial programming adapter.
