Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific part number against official Skyworks documentation to confirm electrical characteristics and pinout compatibility before integration. Ensure that the required supply voltage and load conditions match the system design specifications. Confirm availability through authorized distributors as stock levels may vary. Check for any recent revisions or obsolescence notices directly from the manufacturer.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this component when a wide tuning range and low phase noise are required in space-constrained applications. The LVDS output ensures signal integrity at high frequencies. Consider the 2.5 V operating voltage and 98 mA current consumption for power budget calculations. Verify that the 7x5 mm footprint fits the PCB layout constraints.

Pin ConfigurableSelectable Oscillators Part Context

This VCXO belongs to the Si552 family, which offers various output formats and frequency ranges. The 552FD000455DGR specifically provides LVDS outputs and operates at 2.5 V. Other variants in the series may differ in voltage, output type, or frequency coverage. This model is intended for high-performance clock generation in digital communication systems.

Pin ConfigurableSelectable Oscillators Replacement Considerations

Direct substitutes within the Si552 family include models with similar LVDS outputs and 2.5 V operation, such as 552GD000382DGR or 552CK000353DGR, though specific frequency and current ratings must be verified. Cross-referencing datasheets is essential to ensure functional equivalence.
