Crystals Procurement Notes

Verify the specific suffix codes against official Suntsu Electronics documentation to ensure exact electrical parameters match system requirements. Confirm package dimensions and soldering profiles align with manufacturing capabilities. Request updated datasheets directly from authorized distributors or the manufacturer to validate current production status and compliance certifications before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 38.4 MHz reference is required with tight initial tolerance and broad thermal stability. Ensure the circuit design accommodates the 8 pF load capacitance to maintain accurate frequency output. Compare ESR specifications against driver circuit limitations to prevent oscillation failure. Validate that the 4-SMD footprint fits within the available PCB real estate constraints.

Crystals Part Context

This crystal belongs to the SXT2248 series from Suntsu Electronics, which focuses on standard frequency components for consumer and industrial electronics. The series emphasizes reliability and consistency in mass-produced devices. This specific model represents a common frequency choice for digital interfaces requiring moderate precision without the complexity of active oscillators.

Crystals Replacement Considerations

Direct substitutes must match the 38.4 MHz frequency, 8 pF load capacitance, and 4-SMD package dimensions. Verify that alternative manufacturers offer comparable ±15 ppm tolerance and similar ESR values. Ensure thermal range compatibility if operating in extreme environments. Cross-reference pinout configurations to guarantee mechanical interchangeability.
