Procurement Notes

Verify that the specific part number matches the required frequency and output configuration before ordering. Confirm that the 6-VDFN package type aligns with the PCB footprint design. Ensure that the operating temperature range of -40°C to +85°C meets the environmental requirements of the target application. Check for any specific revision or suffix variations that may affect electrical characteristics or packaging.

Selection Notes

Select this component when a programmable solution with LVDS outputs is required for frequencies up to 460 MHz. Consider the 10 ppm stability specification for applications sensitive to frequency drift. Evaluate the 2.25 V to 3.6 V supply range against the system power architecture. The compact 6-VDFN package makes it suitable for space-constrained designs compared to larger oscillator packages.

Part Context

This part belongs to the DSC8123 series of programmable MEMS oscillators from Microchip Technology. The series is characterized by its ability to provide precise clock signals with low jitter. The BI5 suffix typically denotes specific pinout and package configurations within the product line. These oscillators are engineered to replace traditional quartz crystals and resonators in modern electronic designs.

Replacement Considerations

Direct substitutes include other parts from the DSC8123 family with compatible pinouts and specifications. Verify that alternative components support the same LVDS output format and frequency range. Ensure that replacement parts meet the same 10 ppm stability and temperature range requirements. Cross-reference datasheets to confirm identical package dimensions for mechanical fit.
