Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific frequency requirement against the four available options (622.08MHz, 644.53125MHz, 666.51429MHz, 669.32658MHz) before ordering, as the part number corresponds to a specific configuration. Confirm that the LVPECL output format matches the receiving circuit's input requirements. Ensure the operating temperature range of -40°C to 85°C is suitable for the intended environment.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this component when a stable, low-jitter clock source with configurable frequency options is required in a compact surface-mount package. The Si554 series is designed for applications demanding precise timing in telecommunications and networking. Consider the 130mA maximum supply current for power budget calculations and ensure the 3.3V logic level compatibility with the system design.

Pin ConfigurableSelectable Oscillators Part Context

The 554AC000282DG belongs to the Skyworks Si554 family of pin-configurable/ selectable oscillators. This series provides flexibility by allowing different frequencies through pin settings rather than distinct part numbers. The device utilizes a crystal resonator and is packaged in a standard 8-SMD footprint, making it suitable for dense PCB layouts in modern electronic devices requiring reliable clock generation.

Pin ConfigurableSelectable Oscillators Replacement Considerations

The parameter-equivalent substitute part number is 554AC000282DGR. Verify that the reel packaging variant meets the assembly process requirements if tape-and-reel delivery is necessary.
