RF Receivers Procurement Notes

Verify the specific suffix 'A42' against official Skyworks documentation to confirm pinout and functional compatibility. Check the latest datasheet revision history for any changes in electrical characteristics or recommended operating conditions. Ensure the 40-QFN package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

RF Receivers Selection Notes

Select this component when AM, FM, and RDS reception capabilities are required in a compact form factor. The 40-QFN package suits space-constrained designs. Verify that the 1.5V to 5V supply range aligns with the system power architecture. Confirm that the 130mA receive current consumption fits within the thermal and power budget constraints of the application.

RF Receivers Part Context

This part belongs to the Si476x family of radio receivers from Skyworks Solutions. The family employs RF CMOS technology to deliver high-performance reception in small packages. The SI4761 variant specifically targets AM and FM broadcast bands with additional RDS support, distinguishing it from other family members that may focus on different frequency ranges or feature sets.

RF Receivers Replacement Considerations

Consult the official Skyworks substitution guide for verified alternatives. Cross-reference pinouts and electrical specifications carefully. Generic replacements may not maintain identical RDS decoding performance or sensitivity levels.
