• Communication interface synchronization

Crystals Procurement Notes

Verify the specific suffix EA27 against official Suntsu documentation to confirm package dimensions and termination style. Ensure the required frequency tolerance of ±15ppm meets system requirements. Check RoHS compliance status if environmental regulations apply. Confirm availability through authorized distributors as stock levels fluctuate. Validate that the 20pF load capacitance matches the oscillator circuit design specifications before procurement.

Crystals Selection Notes

Select this component when a 16.384 MHz reference is required for surface-mount designs. The ±15ppm tolerance suits applications needing moderate precision without extreme environmental constraints. Consider the 200 Ohm ESR limit for oscillator circuit compatibility. The 0℃ to +70℃ range defines its suitability for general consumer or industrial electronics rather than harsh outdoor conditions. Compare against higher stability variants if tighter ppm limits are necessary.

Crystals Part Context

This crystal is part of the SXT214 series from Suntsu Electronics, Inc., which provides various frequency options in compact surface-mount packages. The series supports standard clock generation needs for embedded systems. Similar models in the lineup may offer different frequencies or tolerance grades while maintaining the same physical footprint. The SXT214 series emphasizes reliability and cost-effectiveness for mass-produced electronic devices requiring stable timing references.

Crystals Replacement Considerations

Direct substitutes include other 16.384 MHz crystals with identical 4-SMD no-lead footprints and 20pF load capacitance. Verify that replacement parts meet the ±15ppm tolerance and 200 Ohm ESR specifications. Ensure the alternative component supports the same 0℃ to +70℃ operating temperature range. Cross-reference pinout and mechanical dimensions to guarantee board compatibility without redesign.
