RF Receivers datasheet and documents for SI4735-B20-GM

SI4735-B20-GM

RF Receivers Overview

The SI4735-B20-GM is a broadcast AM/FM/SW/LW radio receiver IC manufactured by Skyworks Solutions Inc. It operates within a supply voltage range of 2.7 V to 5.5 V and supports FM frequencies from 76 MHz to 108 MHz, as well as AM, SW, and LW bands. The device utilizes a 3-Wire interface for control and communication. It is housed in a QFN-20 package with dimensions of 3 mm x 3 mm x 0.55 mm. The component functions reliably across an operating temperature range of -20°C to +85°C.

RF Receivers Feature Summary

Supports comprehensive broadcast reception including AM, FM, Shortwave, and Longwave bands
Integrates RDS (Radio Data System) functionality for enhanced signal information
Utilizes a compact QFN-20 surface-mount package for space-constrained designs

RF Receivers Applications

Portable consumer audio devices
In-car infotainment systems
Desktop radio receivers

RF Receivers Procurement Notes

Verify the specific suffix 'B20' against official Skyworks documentation to confirm frequency band coverage and feature set. Ensure compatibility with the required 3-Wire interface protocol during integration. Confirm that the QFN-20 thermal pad requirements are met by the PCB layout design to ensure reliable operation within the specified temperature range.

RF Receivers Selection Notes

Select this component when broad broadcast band coverage including LW and SW is required alongside standard FM/AM reception. Consider the 2.7V to 5.5V supply range for flexible power management options. Evaluate the QFN-20 footprint constraints against available board space. Verify that the 3-Wire interface aligns with the host microcontroller's available communication pins.

RF Receivers Part Context

This part belongs to the Si473x series of single-chip radio tuners designed for low-power applications. It integrates the RF front-end, demodulator, and digital audio processor into a single silicon solution. The series targets portable electronics requiring high-performance radio reception with minimal external components.
