SI4768-A41-AM

RF Receivers Overview

The SI4768-A41-AM is an RF receiver manufactured by Skyworks Solutions Inc., designed for FM broadcast band applications. It operates within a frequency range of 64MHz to 108MHz and supports FM modulation protocols. The device functions with a supply voltage between 1.2V and 3.6V, consuming a receiving current of 130mA. It is housed in a 40-QFN (6x6) package with exposed pad, suitable for surface mount installation. The component is rated for operation across a temperature range of -40°C to 85°C.

RF Receivers Feature Summary

• Integrated single-chip FM radio receiver solution
• Supports standard FM broadcast band reception
• Low power consumption design for portable devices

RF Receivers Applications

• Portable audio players
• Car infotainment systems
• Consumer electronics with FM tuning capabilities

RF Receivers Procurement Notes

Verify the part status as obsolete or not recommended for new designs before procurement planning. Confirm availability through authorized distributors, as stock levels may be limited. Ensure that the 40-QFN package dimensions align with the target PCB footprint. Check for any specific handling requirements related to moisture sensitivity level classification during storage and assembly processes.

RF Receivers Selection Notes

Select this component specifically for FM-only applications requiring low supply voltage operation. Compare against other Skyworks models like the SI4761 if AM or RDS support is required, as those variants offer broader frequency coverage. Ensure the system design accommodates the 130mA current draw during active reception. Verify that the 1.2V to 3.6V input range matches the available power rails in the target application.

RF Receivers Part Context

This part belongs to the Skyworks SI47xx series of integrated radio receivers. Unlike broader spectrum models such as the SI4761 which covers AM and FM bands, the SI4768 focuses exclusively on the FM broadcast segment. It shares similar packaging and interface characteristics with other members of the family but differs in supported modulation types and frequency ranges.

RF Receivers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements should be evaluated based on functional equivalence, specifically FM-only reception capability, QFN-40 package compatibility, and supply voltage range matching.
