Crystals Procurement Notes

Verify the specific part status as this item may be discontinued or unavailable through standard channels. Confirm that the 8pF load capacitance matches the target circuit design requirements. Ensure compatibility with the specified 100 Ohm ESR for proper oscillator startup. Check for valid datasheets to confirm current manufacturing availability and compliance documentation before integration.

Crystals Selection Notes

Select this component when a 20.48 MHz fundamental frequency is required with ±15ppm stability. The 8pF load capacitance must align with the host oscillator circuit's total stray capacitance. Consider the 4-SMD package dimensions for PCB layout constraints. Verify that the -20°C to 70°C operating range meets the environmental conditions of the final application.

Crystals Part Context

This crystal belongs to the CTS 402 series of surface mount devices. The series offers various frequencies and load capacitances within a standardized small outline footprint. These components are engineered for high reliability in mass-produced electronic assemblies requiring precise timing signals.

Crystals Replacement Considerations

Direct substitutes include other 20.48 MHz crystals with 8pF load capacitance and similar ESR values from compatible manufacturers. Ensure replacement parts match the 4-SMD 2x1.6mm package dimensions and maintain the same fundamental mode operation characteristics.
