RF Receivers Procurement Notes

Verify component status as the SI4734-C40-GM is listed as obsolete or end-of-life in public records. Confirm availability of direct substitutes such as the SI4735-D60-GM if production continuity is required. Ensure datasheet alignment with specific design-in requirements before procurement.

RF Receivers Selection Notes

Select this component for designs requiring broad frequency coverage including shortwave. Consider the 20-QFN package size for space-constrained layouts. Verify that the 2.7V to 5.5V supply range matches the system power architecture. Check for alternative packages like the D60 suffix if tape-and-reel processing is preferred over trays.

RF Receivers Part Context

This part belongs to the SI473x series of radio tuners by Skyworks Solutions. It shares architectural similarities with the SI4735 but differs in specific band support configurations. The C40 suffix typically denotes a specific package and temperature grade variant within the broader product family.

RF Receivers Replacement Considerations

Public data identifies the SI4735-D60-GM as a direct substitute for the obsolete SI4734-C40-GM. Verify pinout and functional compatibility before replacement.
