Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact electrical parameters. Ensure the selected variant matches the required load capacitance and temperature range for the target application circuit. Cross-reference the package dimensions with the PCB footprint library to guarantee mechanical compatibility during assembly.

Crystals Selection Notes

Select this component when a 2520 footprint is constrained but superior EMI performance is required compared to standard two-pin packages. The four-pad grounding structure provides necessary shielding for sensitive RF sections. Consider the ±20ppm tolerance sufficient for general synchronization tasks where tighter stability is not mandated.

Crystals Part Context

This part belongs to the SXT224 series, which comprises 2520-sized four-pad ceramic crystals designed for industrial applications. The series offers various frequency and stability options to accommodate different wireless and computing requirements. The four-terminal architecture distinguishes it from basic consumer-grade alternatives by providing improved noise immunity.

Crystals Replacement Considerations

Direct substitutes must match the 14.7456 MHz frequency, 20pF load capacitance, and 4-SMD package. Verify that alternative sources offer identical ESR values and thermal stability ranges to maintain circuit performance without redesign.
