Pin ConfigurableSelectable Oscillators Applications

• Telecommunications base stations requiring precise clock generation
• Datacom equipment utilizing high-speed serial interfaces
• Test and measurement instruments needing stable frequency references

Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific output frequency configuration against the datasheet before ordering, as the part number denotes a configurable family member rather than a fixed frequency value. Confirm that the LVPECL output format aligns with the receiving circuit's input requirements. Ensure the 3.3 V power supply rail meets the minimum voltage specifications for reliable operation under all thermal conditions.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this component when a dual-frequency VCXO with LVPECL outputs is required in a compact surface-mount footprint. Compare the 130 mA maximum current consumption against available power budgets. Consider the ±50 ppm stability requirement relative to system jitter tolerance. Verify compatibility with the 15 pF load capacitance specification for accurate frequency tuning.

Pin ConfigurableSelectable Oscillators Part Context

This model belongs to the Si552 family of pin-configurable oscillators manufactured by Skyworks Solutions. These devices are designed to replace multiple discrete oscillator types by offering configurable frequencies and outputs through pin selection. The 552AD variant specifically utilizes LVPECL signaling, distinguishing it from CMOS or LVDS counterparts within the same physical package dimensions.

Pin ConfigurableSelectable Oscillators Replacement Considerations

The 552AD000555DGR is listed as a parameter-equivalent alternative, differing primarily in tape-and-reel packaging versus cut-tape options.
