• Offers flexible programming capabilities allowing customization of frequency and output specifications.
• Provides low-jitter performance suitable for high-speed digital applications requiring precise timing.

Applications

• High-speed data communication interfaces
• Clock distribution networks
• Test and measurement equipment

Procurement Notes

Verify the specific suffix codes against official Microchip documentation to ensure correct configuration. Confirm that the QFN-4 package dimensions align with your PCB footprint requirements. Check humidity sensitivity levels and reflow soldering profiles prior to assembly. Ensure the selected frequency falls within the supported 10 MHz to 460 MHz range for this variant.

Selection Notes

Select this component when a compact surface-mount solution with LVDS outputs is required. Consider the 10 ppm stability requirement against application needs. Evaluate the 2.25 V to 3.6 V operating voltage against system power rails. Compare the QFN-4 package size against available board space constraints.

Part Context

This part belongs to the DSC8123 series of programmable MEMS oscillators. It shares family characteristics such as LVDS output options and wide frequency ranges. The BI2 suffix indicates specific packaging and configuration details distinct from other series variants like DI5 or BI5.

Replacement Considerations

Direct substitutes include other DSC8123 series variants with matching electrical parameters. Verify pin compatibility and package dimensions before swapping. Consult Microchip's official substitution guide for approved alternatives.
