RF Receivers Procurement Notes

Verify the current lifecycle status before procurement, as this component may be marked as not recommended for new designs. Confirm availability through authorized distributors, noting that standard packaging quantities may apply. Ensure the specific suffix matches the required interface and package configuration for your design implementation.

RF Receivers Selection Notes

Select this component when a dedicated AM/FM receiver with RDS support is required for automotive or industrial environments. Consider the 40-QFN package constraints and the 1.5V to 5V operating voltage range. Verify compatibility with existing I2C interfaces if digital control is needed, though specific interface details are limited in public summaries.

RF Receivers Part Context

This part belongs to the Si476x series of RF receivers from Skyworks Solutions. It shares the core architecture with variants like the SI4763-A42-GMR but differs in packaging and potentially pinout configurations. The series targets high-performance audio reception in compact form factors suitable for modern electronic devices.

RF Receivers Replacement Considerations

Publicly documented similar substitutes include the SI4762-A42-AMR and SI4763-A42-AMR. Verify functional equivalence and pin compatibility before substitution, as these alternatives may differ in packaging type or specific feature sets.
