Crystals Procurement Notes

Verify the specific suffix 'XIAR' against official CTS documentation to confirm tape and reel packaging specifications. Ensure compatibility with existing circuit load capacitance requirements before procurement. Confirm that the 60 Ohm ESR aligns with oscillator design constraints. Validate that the component meets all necessary environmental certifications for the intended deployment region.

Crystals Selection Notes

Select this component when a 48 MHz fundamental frequency with 10pF load capacitance is required. Consider the 60 Ohm ESR value for oscillator stability margins. Evaluate the 4-SMD footprint against available PCB real estate. Compare performance against alternative crystals if tighter frequency tolerances or different temperature ranges are needed for the specific application environment.
