RF Receivers Procurement Notes

Verify the specific suffix 'GM' against the manufacturer's official documentation to confirm the tape-and-reel packaging configuration versus tray options. Ensure that the ordering quantity aligns with the manufacturer's standard factory pack requirements. Confirm moisture sensitivity level handling procedures are followed during storage and assembly to prevent damage to the silicon components.

RF Receivers Selection Notes

Select this component when both traditional FM broadcasting and digital HD Radio signals require simultaneous or selectable reception within the same hardware platform. The integrated nature of the chip reduces external component count compared to discrete solutions. Verify that the host microcontroller can support the required I2C or SPI interface speeds and voltage levels compatible with the 1.62 V to 3.6 V supply range.

RF Receivers Part Context

This part belongs to the SI468x series of radio receivers from Skyworks Solutions. It shares the QFN-48 form factor with other variants in the family but differs in supported broadcast standards. While similar packages exist for AM/FM only models, this specific model is distinguished by its inclusion of HD Radio processing capabilities alongside standard FM reception.
