Crystals Procurement Notes

Verify the specific lot code and manufacturing date against project requirements before procurement. Ensure that the 4-SMD no-lead footprint matches the design board layout precisely. Confirm RoHS compliance documentation is available for regulatory adherence. Cross-reference the 8 pF load capacitance requirement with the target circuit design to ensure proper oscillation conditions are met without additional external components.

Crystals Selection Notes

Select this component when a 38.4 MHz reference is required with tight stability constraints. The ±30 ppm stability makes it suitable for applications sensitive to frequency drift within the -10°C to +70°C range. Consider the 150 Ohm series resistance for impedance matching needs. The small form factor is ideal for space-constrained designs where traditional through-hole crystals cannot fit.

Crystals Part Context

This part belongs to the SXT1148 series of surface mount crystals from Suntsu Electronics. The series offers various frequencies and packages, with the DB17 suffix indicating the specific 4-SMD no-lead configuration. It serves as a critical passive component for establishing clock signals in electronic assemblies, replacing older bulkier crystal variants.

Crystals Replacement Considerations

Direct substitutes include other 38.4 MHz crystals with identical 4-SMD no-lead footprints and similar electrical parameters. Verify that any replacement maintains the ±30 ppm stability and 8 pF load capacitance. Check if alternative manufacturers offer equivalent performance in the same package size to ensure mechanical compatibility.
