RF Receivers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific suffix FM corresponds to the required tape-and-reel packaging configuration. Ensure compliance with RoHS3 standards and check for any product change notices regarding assembly sites or labeling updates prior to procurement.

RF Receivers Selection Notes

Select this receiver for designs requiring broad sub-GHz coverage without complex transceiver overhead. The single-ended interface simplifies PCB layout compared to differential alternatives. Consider the 18.5mA receive current for battery life calculations. Verify that the 128kbps data rate meets application throughput requirements before finalizing the bill of materials.

RF Receivers Part Context

This component belongs to the EZRadio series, leveraging technology from the EZRadioPRO family. It serves as a dedicated receiver solution, distinct from full transceivers like the SI4432. The part is designated as not recommended for new designs, indicating potential end-of-life status or successor availability in the manufacturer's portfolio.
