Procurement Notes

Verify the specific suffix requirements for your design, as ordering suffixes may indicate variations in packaging or testing standards. Confirm that the blank programming state aligns with your integration workflow, as this component requires user initialization. Ensure compatibility with your board's thermal and electrical constraints before finalizing procurement orders.

Selection Notes

Select this component when a wide frequency range up to 460 MHz is required with HCSL outputs. Consider the 6-VDFN package size for space-constrained designs. Verify that the ±25ppm stability meets system timing requirements. Ensure the 2.25V-3.6V supply range matches your available power rails and that the enable feature fits your power sequencing strategy.

Part Context

This part belongs to the DSC8124 series of programmable MEMS oscillators. It shares the same family characteristics but differs in output format and stability specifications from other variants like the DSC8121 or DSC8123. The series provides a scalable solution for replacing multiple fixed-frequency crystals with a single programmable device.

Replacement Considerations

Direct replacements within the same package and specification profile should be sought from the DSC8124 series. Cross-model substitution requires careful verification of output format (HCSL vs LVDS/CMOS) and stability ratings. Ensure any substitute maintains the 6-VDFN footprint and compatible supply voltage range.
