Crystals Procurement Notes

Verify the specific datasheet from Suntsu Electronics to confirm environmental ratings and soldering profiles. Ensure compatibility with PCB footprint dimensions for the 4-SMD package. Cross-reference ESR and load capacitance requirements with the target oscillator circuit design to guarantee stable operation and meet system timing accuracy specifications.

Crystals Selection Notes

Select this component when a 19.2 MHz reference with tight ±10ppm stability is required in a low-profile surface-mount form factor. Consider the 70 Ohm ESR limit when designing the oscillator circuit to ensure sufficient loop gain. Verify that the 8pF load capacitance matches the application's external capacitor values for accurate frequency calibration.

Crystals Part Context

This part belongs to the SXT3248 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and tolerances, utilizing standard SMD packaging for high-volume manufacturing. The FB17 suffix typically denotes specific performance characteristics within the product line, distinguishing it from other variants like FD or FC series members.

Crystals Replacement Considerations

Direct substitutes must match the 19.2 MHz frequency, ±10ppm tolerance, 8pF load capacitance, and 4-SMD package. Verify ESR compatibility, as differences in equivalent series resistance may affect oscillator startup reliability. Check pinout and mechanical dimensions to ensure board-level interchangeability without redesign.
