Crystals Procurement Notes

Verify the specific operating temperature range and frequency tolerance requirements against the datasheet specifications before integration. Confirm that the HC-49/US footprint matches the target PCB layout constraints. Ensure compliance with RoHS3 regulations is documented for final product certification. Cross-reference the manufacturer part number to avoid confusion with similar variants in the CSM1 series.

Crystals Selection Notes

Select this component when a standard 27 MHz fundamental frequency is required with moderate stability needs. The HC-49/US SMD form factor offers a balance between performance and board space efficiency compared to larger through-hole alternatives. Consider the ±30 ppm tolerance sufficient for general clocking applications where higher precision is not critical. Evaluate the 50 Ohm ESR against the oscillator circuit drive level capabilities.
