Oscillators Procurement Notes

Verify the specific suffix codes against official ILSI documentation to ensure correct frequency tolerance and temperature range specifications. Confirm that the ordering part number matches the required package style and output type. Cross-reference the manufacturer's latest datasheet to validate RoHS compliance status and lead finish details before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-profile 3.2x2.5mm footprint is required for high-frequency clock generation. Ensure the design supports the 3.3V operating voltage and accommodates the enable/disable pin requirements. Verify that the 25 ppm stability meets the system timing constraints and that the CMOS output drives are compatible with the receiving logic inputs.
