Procurement Notes

Verify the exact suffix code to confirm package type and temperature rating, as variations exist within the DSC8121 series. Confirm RoHS compliance status through official documentation before integration. Ensure supply voltage requirements align with system design constraints. Check for obsolescence notices or lifecycle changes directly from the manufacturer. Validate that the blank programming state meets project timelines for final configuration.

Selection Notes

Select this component when a wide frequency tuning range up to 170 MHz is required without external components. Consider the 6-SMD package size for space-constrained PCB layouts. Evaluate the ±25ppm stability against system jitter tolerance requirements. Compare power consumption metrics if battery life is a critical design factor. Assess thermal performance capabilities within the specified industrial temperature range.
