Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pin configuration and output type compatibility. Ensure the selected variant matches the required frequency range and supply voltage specifications for the target application circuit. Confirm lead times and minimum order quantities directly with authorized distributors prior to placement.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this component when a wide tuning range VCXO with LVPECL outputs is required in a compact SMD form factor. Consider the 130 mA current consumption and 3.3 V operating voltage during power budget analysis. Verify that the 7 mm x 5 mm footprint aligns with the PCB layout constraints and thermal management requirements of the design.

Pin ConfigurableSelectable Oscillators Part Context

This part belongs to the Si552 series of pin-configurable oscillators manufactured by Skyworks Solutions. The series offers various output formats and frequency ranges tailored for different system requirements. The 552AA000374DGR specifically utilizes the standard 7x5mm package and LVPECL output, distinguishing it from other variants in the lineup that may offer CMOS or differential LVDS outputs.

Pin ConfigurableSelectable Oscillators Replacement Considerations

Direct replacements must be sought within the Skyworks Si552 family to maintain pinout and functional compatibility. Verify that any substitute part number shares the same 7x5mm package dimensions and LVPECL output configuration. Cross-reference the specific ordering suffix to ensure identical electrical characteristics and tuning capabilities.
