Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific output format and frequency parameters against the official datasheet before procurement, as the Si552 series offers multiple variants with different electrical characteristics. Confirm that the CMOS output type aligns with your system requirements, as other models in the series may utilize LVPECL or other interfaces. Ensure the operating voltage and current consumption specifications match your power budget constraints. Cross-reference the package dimensions to confirm compatibility with your PCB footprint design.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this model when a VCXO with a wide tuning range up to 1.4 GHz and CMOS output interface is required. Consider the Si552 series for applications needing pin-configurability to simplify inventory management. Evaluate the 7x5 mm package size against available board space. Compare current consumption and supply voltage tolerances with alternative oscillators to ensure optimal power efficiency and signal integrity for the target application environment.
