Oscillators Procurement Notes

Verify the specific frequency tolerance and operating temperature range required for your application against the datasheet specifications. Confirm that the supply voltage aligns with the 1.8V or 3.3V operational modes. Ensure the PCB footprint matches the 5.0mm x 3.2mm x 1.2mm package dimensions. Check for RoHS compliance requirements if applicable to your manufacturing standards. Validate the enable/disable pin configuration during the design phase.

Oscillators Selection Notes

Select this component when a low-power HCMOS oscillator is required for systems operating within the -40°C to +85°C range. Consider the ±50 ppm frequency stability for general-purpose timing applications. Evaluate the 36µA current draw against battery life requirements for portable devices. Compare the physical size constraints with alternative packages if space is limited. Ensure the input logic levels match the HCMOS output characteristics of the downstream circuitry.
