Crystals Procurement Notes

Verify the specific operating temperature range and detailed electrical parameters against the official Suntsu Electronics datasheet prior to procurement. Ensure that the 4-SMD, No Lead package dimensions align with the target PCB footprint. Confirm that the ±30 ppm stability meets the system's jitter and phase noise requirements. Cross-reference the part number suffixes to ensure exact functional equivalence with existing designs.

Crystals Selection Notes

Select this component when a 38.4 MHz reference signal with ±30 ppm accuracy is required in a space-constrained design. The 13 pF load capacitance must match the oscillator circuit's input capacitance to maintain frequency accuracy. Consider the 100 Ohm ESR value for drive level sensitivity. This part is suitable for applications where standard commercial temperature ranges are sufficient and low-profile mounting is preferred.

Crystals Part Context

This crystal belongs to the SXT21413 series from Suntsu Electronics, which focuses on small-footprint surface-mount resonators. The series offers various frequency options and stability grades. The SXT21413BB27 variant specifically denotes the package style and pin configuration within this product line, distinguishing it from through-hole or larger surface-mount alternatives.

Crystals Replacement Considerations

Direct substitutes must match the 38.4 MHz frequency, ±30 ppm stability, 13 pF load capacitance, and 4-SMD, No Lead package. Verify that alternative manufacturers provide identical ESR values and operating temperature ranges to ensure seamless integration without circuit redesign.
