Procurement Notes

Verify the specific suffix 'CM2' against official Microchip documentation to confirm package dimensions and thermal characteristics. Ensure the programming status aligns with project needs, as this variant may require user initialization. Cross-reference the RoHS compliance status and MSL rating with current manufacturing notices to guarantee assembly process compatibility and environmental adherence.

Selection Notes

Select this model when a wide industrial temperature range of -55°C to 125°C is mandatory. The 3.20mm x 2.50mm footprint suits space-constrained designs. Consider the ±25ppm stability specification against system jitter requirements. Evaluate the 35mA current draw against power budget constraints compared to lower-power alternatives in the same series.

Part Context

This component is part of the DSC8121 family of programmable oscillators. It shares architectural similarities with other variants like the DSC8121AM2 but differs in physical package size and thermal rating. The series is designed to replace traditional quartz crystals with more flexible, software-configurable solutions while maintaining reliability.
