Crystals Procurement Notes

Verify the specific ordering suffix and package variant against the official TXC datasheet to ensure compatibility with the target PCB footprint. Confirm that the required frequency stability of ±30 ppm meets the system timing requirements. Check for RoHS compliance documentation if environmental standards are mandatory for the assembly process. Ensure the 8 pF load capacitance matches the oscillator circuit design specifications.

Crystals Selection Notes

Select this component when a small form factor SMD crystal is required for 12.288 MHz applications. The ±30 ppm stability suits general-purpose timing needs within the -40°C to +85°C range. Consider the 100 Ohm ESR value for oscillator circuit loading calculations. This part is suitable for designs prioritizing compactness over higher precision grades available in larger packages.

Crystals Part Context

This component belongs to the 7M series of seam-sealed quartz crystals from TXC Corporation. The series is characterized by high precision and miniaturization, offering reliability for automotive and industrial markets. The 7M designation indicates a specific family of surface-mount units optimized for automated assembly processes.

Crystals Replacement Considerations

Direct substitutes include other 12.288 MHz SMD crystals with identical 3.2x2.5mm footprints and ±30 ppm stability. Verify pinout compatibility and load capacitance matching before substitution. Cross-reference with similar TXC models or industry-standard equivalents that meet the same electrical and thermal specifications.
