SI4732-A10-GSR

RF Receivers Overview

The SI4732-A10-GSR is a digital CMOS AM/FM/SW/LW/RF receiver integrated circuit manufactured by Skyworks Solutions Inc. It utilizes a patented low-IF architecture to provide complete broadcast tuning and reception from antenna input to digital audio output. The device supports global FM bands (64–108 MHz), AM bands (520–1710 kHz), SW bands (2.3–26.1 MHz), and LW bands (153–279 kHz). Operating on a 2.7V to 3.6V supply, it features an integrated VCO and RDS functionality. Housed in a 16-SOIC package with surface mount installation, it operates within a temperature range of -20°C to 85°C.

RF Receivers Feature Summary

• Integrates complete radio tuning and reception functions using a verified digital low-IF architecture for high-fidelity audio performance.
• Supports multiple frequency bands including AM, FM, Shortwave, and Longwave with integrated RDS capabilities.
• Features an advanced automatic search tuning mechanism for efficient signal acquisition across supported bands.

RF Receivers Applications

• Portable consumer electronic devices requiring compact radio solutions
• Digital audio platforms needing high integration and low component count
• Broadcast receivers utilizing AM, FM, SW, or LW frequency bands

RF Receivers Procurement Notes

Verify the manufacturer designation as Skyworks Solutions Inc., following the acquisition history noted in public records. Confirm the specific suffix GSR indicates tape and reel packaging. Ensure the part number matches the 16-SOIC physical dimensions and electrical specifications for the AM/FM/SW-LW receiver class. Cross-reference the RoHS compliance status and lead-free standards against current official documentation to ensure regulatory adherence for manufacturing integration.

RF Receivers Selection Notes

Select this component when designing systems requiring a single-chip solution for multi-band radio reception. The choice is driven by the need for minimal PCB space, with board area under 15 square millimeters excluding the antenna. Consider the 2-Wire interface compatibility and the requirement for external components limited to those necessary for power decoupling and antenna matching. Evaluate the operating voltage range against the system's power budget.

RF Receivers Part Context

This device belongs to the SI4732 series, leveraging Silicon Laboratories' patented Si4700/01 architecture now managed by Skyworks Solutions. It represents a shift towards highly integrated digital receivers that replace traditional analog front-ends. The series is designed for cost-effective production with simplified design flows and enhanced reliability through complete system production testing protocols established during its development phase.
