SI4632-A10-GMR

RF Receivers Overview

The SI4632-A10-GMR is an RF receiver integrated circuit manufactured by Skyworks Solutions Inc., designed for AM, FM, SW-LW, and RBDS/RDS signal reception. It operates within frequency ranges of 520kHz to 1.71MHz, 76MHz to 108MHz, and 168MHz to 240MHz. The device supports I2C and SPI data interfaces and functions on a supply voltage between 1.71V and 2V. It is housed in a 48-QFN (7x7) surface-mount package with exposed pads, suitable for PCB mounting.

RF Receivers Feature Summary

• Supports multiple broadcast standards including AM, FM, Shortwave, Longwave, and RDS/RBDS protocols.
• Integrates digital radio broadcast reception capabilities within a single silicon component.
• Features flexible digital interface options via I2C and SPI for system control.

RF Receivers Applications

• Digital radio broadcast receivers
• AM/FM/SW-LW tuner modules
• RDS/RBDS decoding systems

RF Receivers Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability through authorized distributors or secondary market channels is required before procurement. Designers should confirm end-of-life status and lead times with suppliers, as standard manufacturing has ceased. Alternative sourcing strategies must be evaluated to ensure supply chain continuity for existing products.

RF Receivers Selection Notes

Engineers selecting this part must account for its discontinued status and limited future availability. The specific A10 suffix indicates the package and tape/reel configuration; verify that the GMR suffix matches the required reel quantity for assembly processes. Ensure the 48-QFN footprint aligns with the PCB layout constraints and that the 1.71V-2V supply range fits the target system power architecture.

RF Receivers Part Context

The SI4632 belongs to Skyworks' Si463x family of digital radio tuners. This series integrates high-performance RF front-end and baseband processing for consumer audio applications. The -A10 variant specifically denotes the QFN package type and reel packaging, distinguishing it from tray-packaged versions like the SI4632-A10-GM.

RF Receivers Replacement Considerations

Public documentation lists the SI4624-A10-GMR as a related alternative within the same product line. Both devices share similar QFN-48 packaging and interface types. However, the SI4624 focuses on FM/DAB/DAB+ reception rather than the broader AM/LW/SW support of the SI4632. Verify functional compatibility before substitution.
