Crystals Procurement Notes

Verify the specific suffix 'CKR' against the manufacturer's current datasheet to confirm active status and availability, as product lifecycles may change. Ensure the ordering part number matches the required tape and reel quantity specified by CTS-Frequency Controls. Cross-reference the lead time and minimum order requirements directly with authorized distributors prior to procurement planning.

Crystals Selection Notes

Select this component when a 54 MHz fundamental frequency with ±30 ppm stability is required for space-constrained designs. The 8 pF load capacitance must match the oscillator circuit's external capacitor values. Consider the 60 Ohm ESR limit to ensure reliable startup conditions within the target application's oscillator topology.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals, designed for general-purpose timing applications. The series offers various frequencies and packages, with the 402F54033CKR specifically addressing the 54 MHz niche using a standard 2.00mm x 1.60mm footprint compatible with high-volume SMT processes.
