SI4766-A50-AMR

RF Receivers Overview

The SI4766-A50-AMR is an automotive-qualified AM/FM radio receiver integrated circuit manufactured by Skyworks Solutions. It supports global FM frequencies from 64 MHz to 108 MHz and AM bands from 520 kHz to 1710 kHz, including HD Radio capabilities. The device features an integrated active splitter for FM antenna sharing and advanced RDS/RBDS demodulation. Operating within a temperature range of -40°C to +85°C, it utilizes a 40-QFN (6x6 mm) surface-mount package. The component requires a supply voltage between 2.7 V and 5.5 V with a typical operating current of 130 mA.

RF Receivers Procurement Notes

Verify the specific suffix AMR against official Skyworks documentation to confirm tape-and-reel packaging requirements. Confirm that the AEC-Q100 automotive grade designation aligns with your system's environmental standards. Check for obsolescence notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

RF Receivers Selection Notes

Select this component when designing automotive audio systems requiring certified reliability and global band coverage. Ensure the design accommodates the 40-QFN thermal pad requirements and the specified 2.7V to 5.5V power supply range. Verify compatibility with existing antenna architectures given the integrated active splitter feature.

RF Receivers Part Context

This part belongs to the SI476x family of single-chip AM/FM radio receivers designed for high-performance audio applications. The series is widely adopted in the automotive industry due to its integration of RF front-end, baseband processing, and digital interfaces into a compact footprint, simplifying board layout and reducing component count.

RF Receivers Replacement Considerations

Official substitutes include the SI4766-A50-GMR and SI4766-A20-GM. Verify pinout compatibility and packaging differences, such as tray versus cut tape, when transitioning between these variants.
