RF Receivers Procurement Notes

Verify the specific suffix 'AMR' indicates tape-and-reel packaging rather than tray or cut-tape formats. Confirm that the AEC-Q100 automotive qualification status aligns with your design requirements. Check current availability as this part may be subject to obsolescence notices or limited stock conditions. Ensure the 40-QFN footprint matches your PCB layout constraints before ordering.

RF Receivers Selection Notes

Choose this component when a complete AM/FM/RDS solution is required for automotive platforms. The integrated nature reduces external component count compared to discrete solutions. Consider the 40-QFN package size for space-constrained designs. Verify compatibility with existing microcontroller interfaces for control and data output. Evaluate power consumption against system battery requirements.

RF Receivers Part Context

This receiver belongs to the Si476x series of broadcast radio ICs. It shares architectural similarities with other models in the family but offers specific frequency coverage and interface options. The Si4763 variant is tailored for standard automotive radio implementations. It complements other Skyworks wireless solutions by providing dedicated broadcast tuning capabilities.

RF Receivers Replacement Considerations

Publicly documented similar alternatives include the SI4762-A42-AMR and SI4763-A42-AMR. These parts offer comparable functionality within the same series. Verify pinout and software compatibility before substituting. Other series members like the Si4755 provide different feature sets.
