Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific frequency configuration and pinout requirements against your schematic before ordering. Confirm that the LVPECL output compatibility matches your receiver inputs. Ensure the 3.3 V power supply rails meet the current specifications. Check the lead time availability as manufacturing cycles may vary. Validate the package dimensions fit your PCB footprint constraints.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this model when dual-frequency capability and LVPECL outputs are required in a small form factor. Consider the ±100 ppm stability for applications tolerant of moderate phase noise. Compare against other Si552 variants if different output formats like CMOS or LVDS are needed. Evaluate thermal performance within the -40°C to +85°C range for your environment.

Pin ConfigurableSelectable Oscillators Part Context

This part belongs to the Skyworks Si552 family of VCXOs, which are known for their flexibility and low power consumption. The 552AA000985DG specifically utilizes the LVPECL output option, distinguishing it from CMOS or LVDS variants within the same series. It shares the standard 7x5 mm package footprint common to the family.

Pin ConfigurableSelectable Oscillators Replacement Considerations

Direct substitutes include other 552AA series parts with matching LVPECL outputs and similar frequency ranges. Verify pin compatibility for cross-referencing with alternative manufacturers' offerings.
