Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct configuration. Confirm that the required supply voltage aligns with the 1.71 V to 1.89 V operational range. Check package dimensions against PCB footprint requirements. Ensure environmental specifications meet the -40°C to +85°C operating temperature criteria for the intended application environment.

Selection Notes

Select this component when a low-profile surface-mount oscillator is required for timekeeping applications. Consider the ±25 ppm stability requirement against system timing accuracy needs. Evaluate the 1.5 mA maximum current consumption against total system power budgets. Verify compatibility with the 1.8V logic levels and enable pin requirements of the host microcontroller or processor.
