Crystals Procurement Notes

Verify the exact frequency stability specification required for your application, as datasheets indicate variations between ±10ppm and ±20ppm for this part number family. Confirm that the 100 Ohm ESR aligns with your oscillator circuit design requirements. Ensure the 12pF load capacitance matches the target IC input specifications. Cross-reference the physical package dimensions to verify board space compatibility before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 38.4 MHz fundamental frequency is specifically required for digital timing applications. The choice depends on matching the 12pF load capacitance to the host circuit's input characteristics. Consider the 100 Ohm ESR value against the driving capability of the connected oscillator chip. Evaluate the ±10ppm or ±20ppm stability tolerance against the system's jitter and phase noise requirements to ensure reliable long-term operation.

Crystals Part Context

This part belongs to the SXT11412 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and stability grades within a standardized small footprint. Similar models include variants with different ESR values or temperature ranges, such as the SXT11412ED16 series. The numbering convention typically indicates frequency and package type, allowing engineers to scale designs across the product line while maintaining mechanical consistency.

Crystals Replacement Considerations

Direct substitutes must match the 38.4 MHz frequency, 12pF load capacitance, and 4-SMD no-lead package. Verify that alternative components support the same 100 Ohm ESR limit. Check if the replacement offers compatible ±10ppm or ±20ppm stability. Ensure the substitute is also RoHS compliant. Generic crystals with different ESR or capacitance values may require circuit redesign.
