Crystals Procurement Notes

Verify the specific suffix requirements against the official datasheet before ordering, as packaging or temperature variants may differ. Confirm that the selected part number aligns with current manufacturing availability, as components in this series may be subject to discontinuation or supply limitations. Ensure compatibility with existing PCB footprints and reflow profiles.

Crystals Selection Notes

Select this component when a 40.61 MHz fundamental frequency is required in a small form factor. Consider the 18pF load capacitance requirement for circuit design matching. Evaluate the ±20ppm tolerance against system jitter specifications. The 60 Ohm ESR value should be compatible with the driving circuit's impedance constraints.
