Oscillators Procurement Notes

Verify the specific suffix codes against official SiTime documentation to ensure correct voltage, package, and tolerance specifications. Confirm that the ordering part number matches the required frequency and output logic level for your design. Check RoHS compliance status if restricted substances are a constraint. Ensure the supplier provides valid traceability documents for quality assurance purposes.

Oscillators Selection Notes

Select this model when a 10.24 MHz reference is required in harsh thermal environments. The ±25 ppm stability suits general digital interfaces where extreme precision is not critical. The 3.3V supply aligns with standard logic families. Consider the enable pin utility if system power conservation is necessary during idle states.

Oscillators Part Context

This component belongs to the SiT8918 series of high-temperature MEMS oscillators. The series is designed to replace traditional quartz devices in demanding applications. The BA suffix indicates the specific package and performance tier within the product family. These devices offer improved shock resistance compared to mechanical resonators.

Oscillators Replacement Considerations

SiTime Time Machine II programmers can configure field-programmable devices to match legacy quartz specifications. Verify pin compatibility and footprint dimensions before substitution. Ensure the replacement device supports the required operating temperature range and output voltage levels.
