• Embedded systems clock generation

Crystals Procurement Notes

Verify that the specific 120 Ohm ESR requirement aligns with the oscillator circuit design, as this value differs from standard lower-resistance crystals. Confirm the HC-49/US SMD footprint compatibility on the PCB. Ensure the operating temperature range of -10°C to +60°C meets the environmental conditions of the target application. Cross-reference the 18 pF load capacitance with the host system's requirements.

Crystals Selection Notes

Select this component when a higher ESR of 120 Ohms is necessary for the specific oscillator topology or drive level constraints. The HC-49/US SMD package offers a balance between mechanical robustness and space efficiency compared to smaller footprints. Consider the ±30 ppm tolerance if tighter frequency accuracy is not required, allowing for cost-effective solutions in general-purpose timing applications.
