Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the exact part number suffix against official Skyworks documentation to confirm packaging type and electrical specifications. Ensure compatibility with system voltage and thermal requirements. Confirm lead-free status and RoHS compliance if required by project standards. Cross-reference pin configurations to avoid layout errors during PCB design.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this component when dual frequency generation is required with LVPECL outputs. Consider the 130 mA current draw for power budgeting. Evaluate the ±20 ppm stability against system jitter requirements. Ensure the 7x5 mm footprint fits within the mechanical constraints of the target enclosure.

Pin ConfigurableSelectable Oscillators Part Context

This oscillator belongs to the Si552 family of pin-configurable VCXOs. It offers flexibility in frequency selection and output configuration. The dual frequency feature allows for multiple clock sources in a single package, reducing component count and board space compared to using separate oscillators.

Pin ConfigurableSelectable Oscillators Replacement Considerations

The 552AJ000177DGR is a parameter-equivalent alternative offered in reel packaging instead of cut tape. Verify that the reel quantity matches production needs. No other direct substitutes are documented in public sources.
