- General purpose RF reception
RF Receivers Procurement Notes
Verify the specific suffix 'AMR' indicates tape and reel packaging rather than tray. Confirm current availability status as some variants show restricted supply. Ensure compatibility with existing PCB footprints and power requirements before ordering.
RF Receivers Selection Notes
Choose this model for applications requiring automotive qualification and multi-band support including shortwave. Compare against SI4755 if RDS is not needed or SI4757 for different band configurations. Verify package dimensions match design constraints.
RF Receivers Part Context
Part of the SI47xx series by Skyworks Solutions. This family includes similar receivers like SI4755 and SI4757. The SI4756 specifically adds Shortwave and Longwave capabilities compared to basic AM/FM models. It is designed for high integration in consumer and automotive electronics.
RF Receivers Replacement Considerations
SI4756-A40-AM is the tray-packaged equivalent. SI4755-A40-AMR offers similar features without SW/LW. SI4757-A40-AM provides alternative band coverage. Check datasheets for pin-to-pin compatibility and functional differences.
