RF Receivers Procurement Notes

Verify the specific suffix GMR indicates tape and reel packaging when sourcing components. Confirm that the selected variant meets the required voltage supply specifications for the target application. Ensure compatibility with the 40-pin QFN footprint during PCB layout. Check current availability status as automotive grade components may have restricted supply conditions.

RF Receivers Selection Notes

Select this component for designs requiring certified automotive reliability in compact form factors. Compare against SI4762-A42-GMR if SW/LW band support is necessary. Verify interface compatibility with the host microcontroller before finalizing the bill of materials. Consider thermal management requirements due to the exposed pad package design.

RF Receivers Part Context

This part belongs to the Si476x series of high-performance RF receivers from Skyworks Solutions. The series targets automotive markets with integrated solutions for broadcast radio. The SI4763 variant specifically focuses on AM/FM/RDS capabilities without shortwave support. It complements other family members like the SI4768 which offers HD Radio functionality.

RF Receivers Replacement Considerations

SI4763-A42-GM is the tray-packaged equivalent of this component. SI4762-A42-GMR serves as a functional alternative if additional shortwave band coverage is required.
