RF Receivers Procurement Notes

Verify the specific suffix (GM vs GMR) determines the packaging format, as GM typically indicates tray packaging while GMR indicates reel packaging. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for your assembly process. Ensure the supplier provides valid datasheets from Skyworks Solutions Inc., noting that Silicon Labs was the original manufacturer before acquisition. Check lead times as they may vary based on production cycles.

RF Receivers Selection Notes

Select this component when designing for multi-standard digital radio reception in compact form factors. The 48-QFN package suits space-constrained PCB layouts. Ensure the host system can provide the required 1.62 V to 2 V power rail. Verify interface compatibility with the microcontroller using I2C or SPI. Consider thermal management within the specified -40°C to +85°C range for automotive or outdoor deployments.

RF Receivers Part Context

The SI4684 belongs to a family of CMOS digital radio broadcast receiver ICs originally developed by Silicon Laboratories. Following Skyworks Solutions' acquisition, these products are now marketed under Skyworks. This series integrates RF front-end and baseband processing into a single chip, reducing external component count compared to discrete solutions.

RF Receivers Replacement Considerations

Check SI4684-A10-GMR for identical functionality with different reel packaging. Verify SI4684 variants with different suffixes for potential pinout or feature differences. Cross-reference with other Skyworks Si46xx series receivers for direct replacements if available.
