RF Receivers Procurement Notes

Verify the specific suffix 'AMR' against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the required supply voltage range of 2.7V to 5.5V for the target application. Confirm that the 40-QFN footprint matches the PCB layout design. Check for any recent Product Change Notifications regarding assembly sites or material composition updates from Skyworks Solutions Inc.

RF Receivers Selection Notes

Select this component for applications requiring certified automotive-grade RF reception. The integrated HD Radio tuner capability distinguishes it from standard FM/AM receivers. Consider the 40-QFN package dimensions for space-constrained designs. Verify that the operating temperature range of -40°C to +85°C meets environmental requirements. Compare power consumption metrics against system battery constraints if applicable.

RF Receivers Part Context

This part belongs to the Si476x series of RF receivers from Skyworks Solutions Inc. The series includes various models tailored for different radio reception needs, such as the SI4763 and SI4768. The SI4762 variant specifically focuses on AM/FM and HD Radio functionality. It is distinct from the discontinued SI4762-A50-GMR which had different electrical characteristics.

RF Receivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Cross-reference with other members of the Si476x family, such as the SI4763-A42-AMR, only if pinout and functional compatibility are verified through official datasheets.
