Crystals Procurement Notes

Verify the specific suffix ED07 against the manufacturer's current datasheet to confirm pinout and tape/reel specifications. Ensure the operating temperature range aligns with the target application environment. Cross-reference the 80 Ohm ESR value with the oscillator circuit design requirements to guarantee proper startup conditions and sustained oscillation amplitude.

Crystals Selection Notes

Select this component when a 24.576 MHz reference is required with ±15 ppm tolerance. The 18 pF load capacitance must match the external circuit loading. Consider the 4-SMD form factor for space-constrained designs. Evaluate the 80 Ohm ESR against the driving capability of the host oscillator IC to prevent over-driving or failure to start.

Crystals Part Context

This part belongs to the SXT224 series of HC-49/US style surface-mount crystals from Suntsu Electronics. The series offers various frequency options and tolerance levels. The SXT22418ED07 variant specifically targets applications requiring moderate stability in a compact surface-mount package, bridging the gap between through-hole reliability and modern SMD assembly efficiency.

Crystals Replacement Considerations

Direct substitutes include the SXT22418FD07-24.576M, which offers tighter ±10 ppm tolerance, and the SXT22418BB07-24.576M, which provides ±30 ppm tolerance. Verify that the alternative part maintains the same 18 pF load capacitance and 80 Ohm ESR characteristics to ensure circuit compatibility.
