Crystals Procurement Notes

Verify the specific suffix configuration against the manufacturer's current datasheet to ensure compatibility with design requirements. Confirm that the ordering part number matches the exact frequency and tolerance specifications needed for the target application. Cross-reference the RoHS compliance status and any regional supply restrictions before finalizing procurement plans.

Crystals Selection Notes

Select this component when a precise 55.46667 MHz reference is required within strict spatial constraints. The AEC-Q200 qualification makes it suitable for applications demanding high stability under thermal stress. Ensure the circuit design accounts for the 9 pF load capacitance and limits drive levels to prevent frequency shifts or mechanical damage during operation.

Crystals Part Context

This model belongs to the AV series of automotive crystals from TXC Corporation. The series utilizes glass-sealing technology to enhance environmental resistance compared to standard epoxy-sealed units. It is designed specifically for high-reliability sectors where long-term frequency stability and vibration resistance are critical performance indicators.

Crystals Replacement Considerations

Direct substitutes must match the 55.46667 MHz frequency, 9 pF load capacitance, and 3.2x2.5 mm package dimensions. Verify that alternative sources also hold AEC-Q200 certification if automotive usage is intended. Check for equivalent temperature stability and aging rates to maintain system timing integrity.
