Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific suffix 'DG' against official Skyworks documentation to confirm lead-free status and tape/reel packaging specifications. Ensure the ordering part number matches the exact frequency configuration required, as variants within the Si554 family differ significantly in output frequencies despite shared electrical characteristics. Cross-reference the datasheet revision date to ensure compliance with current manufacturing standards.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this component when precise timing is required for wireless base stations or test instruments. The LVPECL output is suitable for high-speed digital interfaces. Consider the 15 pF load capacitance for PCB layout matching. Evaluate the 130 mA current consumption against system power budgets compared to CMOS or CML alternatives in the same series.
