Oscillators Procurement Notes

Verify the specific package dimensions and pin configuration against the official datasheet before integration, as variations may exist between manufacturing batches. Ensure that the load capacitance requirements of the host circuit match the component's specified 20 pF to maintain frequency accuracy. Confirm temperature range specifications align with the operational environment of the final product to guarantee long-term reliability.

Oscillators Selection Notes

Select this component when a 40 MHz reference is required in a minimal footprint application. Consider the ESR value of 30 Ohms to ensure compatibility with the oscillator circuit's drive level constraints. Evaluate the thermal performance characteristics if the device will operate in environments with significant temperature fluctuations, as crystal frequency can drift with temperature changes.
