Crystals Procurement Notes

Verify the specific load capacitance requirement against the target oscillator circuit design to ensure frequency accuracy. Confirm that the driving voltage levels remain within the specified 100 µW limit to prevent frequency shifts or crystal damage. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to guarantee proper solder joint formation and mechanical stability during operation.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency is required with tight ±10 ppm tolerance specifications. Consider the 8 pF load capacitance requirement carefully to match the external capacitors in the oscillator circuit. Evaluate the 40 Ohm ESR limit against the oscillator driver strength to ensure reliable startup conditions under all environmental temperatures.
