SI47972A0GE1AMR

RF Receivers Overview

The SI47972A0GE1AMR is a high-performance automotive dual RF receiver manufactured by Skyworks Solutions Inc. It supports AM, FM, SW-LW, RBDS/RDS, DAB/DAB+, DMB, and DRM tuning. The device operates within frequency ranges of 144kHz to 288kHz, 520kHz to 1.71MHz, 2.3MHz to 30MHz, 64MHz to 108MHz, and 168MHz to 240MHz. It utilizes I2C and SPI data interfaces and is housed in a 56-VFQFN package with dimensions of 8x8 mm. The component is AEC-Q100 qualified for automotive applications.

RF Receivers Feature Summary

• Dual receiver architecture supporting simultaneous or independent operation
• Integrated digital radio tuner capabilities for DAB/DAB+ and DRM standards
• Automotive-grade reliability certified under AEC-Q100 standards
• Supports multiple modulation protocols including AM, FM, and RDS

RF Receivers Applications

• In-vehicle infotainment systems requiring multi-band reception
• Digital audio broadcasting receivers for automotive navigation units
• High-performance car stereo tuners supporting legacy and digital formats
• Telematics control modules with integrated radio functionality

RF Receivers Procurement Notes

Verify the specific suffix 'R' indicates reel packaging configuration when sourcing. Confirm that the AEC-Q100 qualification aligns with target automotive temperature grades. Ensure interface compatibility with the host microcontroller's I2C or SPI controller. Validate that the 56-QFN thermal pad requirements are met by the PCB layout design prior to procurement.

RF Receivers Selection Notes

Select this component for designs requiring integrated support for both analog FM/AM and digital DAB/DRM signals in a single package. Consider the 56-pin QFN footprint constraints against available board space. Evaluate the need for dual receiver channels versus single-channel alternatives like the SI47951 series if cost or pin count is critical. Verify power supply voltage levels match the system's 1.8V or 3.3V rails.

RF Receivers Part Context

This part belongs to the SI479xx family of high-performance automotive radio tuners from Skyworks Solutions. It complements other models such as the SI47962 and SI47951, offering enhanced digital radio capabilities compared to earlier generations. The family is designed specifically for modern automotive audio environments demanding robust signal processing and multi-standard support.

RF Receivers Replacement Considerations

The SI47972A0GE1AM is a non-reel variant of the same functional device. For single-channel applications, the SI47951 series may serve as a functional alternative if digital radio support is not required.
