SI4760-A50-AMR

RF Receivers Overview

The SI4760-A50-AMR is an automotive-qualified AM/FM radio receiver from Skyworks Solutions, designed for global frequency coverage. It supports FM bands from 64 MHz to 108 MHz and AM bands from 520 kHz to 1.71 MHz. The device integrates RDS/RBDS decoding and digital FM MPX processing. Operating within a voltage range of 1.5 V to 5 V, it consumes 130 mA during reception. The component is housed in a 40-QFN package measuring 6 mm x 6 mm with a height of 0.85 mm. It functions reliably across temperatures from -40°C to +85°C.

RF Receivers Feature Summary

• Supports global AM and FM broadcast band reception including HD Radio capabilities
• Integrates advanced RDS/RBDS demodulator and decoder functionality
• Includes digital FM MPX decoder for high-fidelity audio processing
• Features integrated FM active splitter for antenna signal distribution

RF Receivers Applications

• Automotive infotainment systems requiring AEC-Q100 compliance
• Global AM/FM radio receivers supporting multiple regional standards
• Audio processing units utilizing digital MPX decoding
• Embedded radio modules with RDS data handling requirements

RF Receivers Procurement Notes

Verify the specific suffix (AMR vs GM) against the original design specification, as packaging formats differ between tape-and-reel and cut-tape configurations. Confirm that the obsolete status does not impact long-term supply chain stability for existing production lines. Ensure the QFN-40 footprint matches the PCB layout exactly, particularly regarding the exposed pad thermal connection. Cross-reference the AEC-Q100 qualification level if the application demands strict automotive reliability standards beyond standard industrial grades.

RF Receivers Selection Notes

Choose this component when global AM/FM coverage is required alongside integrated RDS processing. The 1.5 V to 5 V supply range offers flexibility for various system power architectures. The 130 mA current draw is suitable for battery-operated or low-power automotive applications. Consider the 40-QFN package size if board space is constrained. Verify compatibility with the host microcontroller's I2C interface for control and configuration.

RF Receivers Part Context

This part belongs to the Si476x family of single-chip radio tuners from Skyworks Solutions. It is specifically engineered for automotive and consumer audio applications requiring high integration. The SI4760 variant focuses on AM/FM reception with HD Radio support, distinguishing it from other family members that may include shortwave or longwave capabilities. It represents a consolidated solution replacing discrete tuner and decoder components.

RF Receivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation due to the obsolete status of the SI4760-A50-AMR. Designers should consult Skyworks Solutions directly for potential next-generation replacements or compatible alternatives within the Si47xx series.
