SI4761-A42-GMR

RF Receivers Overview

The SI4761-A42-GMR is an AM/FM/RDS radio receiver integrated circuit manufactured by Skyworks Solutions Inc. It operates within frequency ranges of 520kHz to 1.71MHz for AM and 64MHz to 108MHz for FM. The device supports a supply voltage between 1.5V and 5V, with a typical receive current of 130mA. It is housed in a 40-QFN (6x6) package designed for surface mount installation. The component functions as an RF receiver suitable for audio applications.

RF Receivers Feature Summary

• Integrates advanced analog front-end filtering and digital signal processing to mitigate adjacent-channel interference.
• Supports RDS data reception alongside standard AM and FM broadcast bands.

RF Receivers Applications

• Audio streaming devices
• Car audio systems

RF Receivers Procurement Notes

Verify the specific suffix 'A42' against official Skyworks documentation to confirm functional differences from other variants like A20 or A41. Ensure compatibility with the required 40-QFN footprint and verify that the 1.5V to 5V supply range meets system power constraints. Confirm availability status as distribution channels may report limited stock or discontinuation notices.

RF Receivers Selection Notes

Select this component when adjacent-channel interference mitigation is critical for audio clarity in AM/FM reception. The integrated digital signal processing reduces external filter requirements compared to older architectures. Ensure the design accommodates the 130mA operating current and the specific thermal characteristics of the 40-QFN package for reliable performance.
