Crystals Procurement Notes

Verify the specific suffix 'HQ' against the official TXC datasheet to confirm the extended temperature range (-40°C to +85°C) and pin configuration. Ensure the ordering quantity aligns with standard reel sizes if bulk procurement is required. Cross-reference the manufacturer part number with distributor catalogs to avoid confusion with similar variants in the 7V series that may differ in load capacitance or tolerance specifications.

Crystals Selection Notes

Select this component when a precise 55.46667 MHz reference is required with ±30 ppm stability. The 10 pF load capacitance must match the oscillator circuit design. Consider the 4-SMD package size constraints during PCB layout. Verify that the application environment falls within the specified -40°C to +85°C operational limits to ensure long-term frequency accuracy and reliability.

Crystals Part Context

This part belongs to the 7V series of ceramic crystals from TXC Corporation. The series is characterized by small form factors suitable for modern electronics. The 7V-55.466670MAHQ-T specifically targets applications requiring high-frequency stability in compact designs, distinguishing it from larger through-hole or lower-frequency alternatives in the broader product portfolio.

Crystals Replacement Considerations

Direct substitutes include other 55.46667 MHz crystals with identical 10 pF load capacitance and ±30 ppm tolerance. Check for equivalent SMD packages (3.2x2.5mm) and matching temperature ranges. Verify ESR values and drive level requirements to ensure circuit compatibility without redesign.
