Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required load capacitance and tolerance specifications. Confirm that the ECX-1247 series designation matches the intended PCB footprint and reflow soldering profile requirements for the target assembly process.

Crystals Selection Notes

Select this component when a precise 38.4 MHz reference is required in space-constrained designs. The 10 pF load capacitance must align with the oscillator circuit design. Consider the ±10 ppm stability requirement relative to system timing accuracy needs and verify the -20°C to +70°C operating range suits the environmental conditions.

Crystals Part Context

This part belongs to the ECX-1247 series of SMD crystals from ECS Inc. International. The series offers various frequency options in a standardized small outline package. The CKM-TR suffix indicates the specific packaging configuration for automated assembly processes.

Crystals Replacement Considerations

Direct substitutes include components with identical 38.4 MHz frequency, 10 pF load capacitance, and compatible package dimensions. Verify ESR values and stability ratings match system requirements before substitution.
