Crystals Procurement Notes

Verify the specific ordering suffix 'CKR' against the official CTS datasheet to ensure correct packaging and terminal finish specifications. Confirm that the 8 pF load capacitance requirement matches the target circuit design before procurement. Check current availability status as distribution channels may report varying stock levels or discontinuation notices.

Crystals Selection Notes

Select this component when a 20.48 MHz fundamental mode crystal is required in a 2016 SMD package. Ensure the application circuit provides the specified 8 pF load capacitance to achieve the rated ±10 ppm stability. Verify that the operating environment remains within the -20°C to +70°C range and that the 100 Ohm ESR is compatible with the oscillator driver circuit.
