Crystals Procurement Notes

Verify the specific frequency tolerance requirement against the datasheet, as standard values may vary by configuration. Confirm that the 9pF load capacitance matches the target circuit design parameters. Ensure the operating temperature range of -20°C to 70°C aligns with the intended application environment. Check for any specific handling requirements related to the surface mount package type during assembly.

Crystals Selection Notes

Select this component when a precise 20.48 MHz reference is required in a compact footprint. Consider the ±30ppm stability for general timing applications where high precision is not critical. Evaluate the 100 Ohm ESR against oscillator circuit drive level constraints. Compare physical dimensions against available PCB real estate to ensure compatibility with the 4-SMD package.
