Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with reflow soldering profiles defined in the component's thermal handling guidelines. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 54 MHz reference signal with ±10 ppm stability is required. The 18 pF load capacitance must match the oscillator circuit design to ensure accurate frequency operation. Consider the 60 Ohm ESR limit when evaluating drive level sensitivity and circuit loading effects in the target application environment.

Crystals Part Context

This crystal belongs to the standard SMD crystal family from CTS-Frequency Controls, which provides various frequency options in similar footprints. The 402 series offers a balance between size constraints and electrical performance for general-purpose timing needs. It complements larger through-hole crystals and more complex active oscillators in mixed-signal designs.

Crystals Replacement Considerations

Direct substitutes include other 54 MHz SMD crystals with matching 18 pF load capacitance and ≤60 Ohm ESR. Verify pinout compatibility and mechanical dimensions before substitution. Alternative part numbers from different manufacturers require validation of frequency stability and temperature coefficients.
