Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific suffix 'DG' against official Skyworks documentation to confirm tape-and-reel packaging requirements versus cut-tape availability. Confirm that the requested frequency option matches the exact part number designation, as the Si554 series offers multiple frequency variants within the same package. Ensure compatibility with 3.3V logic levels and LVPECL interface requirements before procurement.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this component when LVPECL output is required for high-speed differential signaling applications. Consider the ±20ppm stability specification against system jitter requirements. Evaluate the 130mA maximum current draw against available power budget constraints. Verify that the 7x5mm footprint fits within the PCB layout restrictions compared to larger oscillator packages.

Pin ConfigurableSelectable Oscillators Part Context

The 554AH000331DG belongs to the Si554 family of VCXOs, designed for precision timing in demanding environments. This series provides flexible frequency options and configurable outputs, making it suitable for complex clocking architectures. The 'AH' variant specifically denotes LVPECL output characteristics within the broader product line.

Pin ConfigurableSelectable Oscillators Replacement Considerations

The parameter-equivalent substitute is 554AH000331DGR, which shares identical electrical specifications but differs in packaging format.
