RF Receivers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm that the specific suffix matches the required revision level for your design. Check for moisture sensitivity handling requirements during storage and assembly. Ensure compatibility with existing BOM constraints regarding package dimensions and thermal characteristics before finalizing procurement plans.

RF Receivers Selection Notes

Choose this component when minimizing board space is critical for FM reception tasks. The integrated RDS functionality eliminates the need for separate decoders. Consider the 16-QFN package size against available PCB real estate. Evaluate the 21.1mA current consumption against battery life requirements for portable applications. Verify that the 2.7V minimum supply voltage aligns with the system power architecture.
