Crystals Procurement Notes

Verify the specific ordering suffix against official CTS documentation to ensure correct electrical parameters, as suffixes may indicate variations in tolerance or packaging. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into production workflows. Cross-reference datasheet specifications with current inventory availability through authorized distributors.

Crystals Selection Notes

Select this component when a 54 MHz fundamental frequency crystal is required with low ESR characteristics suitable for standard oscillator circuits. Ensure the load capacitance matches the circuit design requirements. Consider the operating temperature range and physical footprint constraints during the initial schematic capture phase to guarantee compatibility with the target application environment.
