• Frequency standards for digital logic circuits

Crystals Procurement Notes

Verify the specific ordering suffix and package variant against the official TXC datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status and lead-free specifications prior to procurement. Check for any recent product discontinuation notices or lifecycle changes directly from the manufacturer to avoid supply chain disruptions during production.

Crystals Selection Notes

Select this component when a 14.31818 MHz reference is required for systems needing ±30 ppm stability within a -20°C to +70°C environment. Ensure the circuit design accommodates the 18 pF load capacitance and 100 Ohm ESR limits. Compare physical dimensions against available board space to confirm the 2.5mm x 2.0mm package fits the layout constraints without interference.

Crystals Part Context

This part belongs to the TXC 8Z series of SMD seam sealing crystals. The series is characterized by high-frequency stability and robust construction suitable for industrial and commercial applications. The 8Z series provides a reliable alternative to through-hole crystals while maintaining similar electrical performance characteristics in a smaller form factor.

Crystals Replacement Considerations

Direct substitutes include other 14.31818 MHz SMD crystals with matching 18 pF load capacitance and ±30 ppm stability. Verify package dimensions and pin configuration compatibility before substitution. Cross-reference with TXC's 7A or 9B series if different packaging or temperature ranges are acceptable.
