RF Receivers Procurement Notes

Verify the specific suffix 'GM' indicates the tray packaging variant when sourcing. Confirm that the part meets current automotive quality standards if used in safety-critical designs. Check for any recent production change notices regarding the Si476x series. Ensure the design accounts for the required supply voltage ranges specified in the datasheet. Validate compatibility with the host controller's I2C/I2S interface timing requirements before finalizing the bill of materials.

RF Receivers Selection Notes

Select this component for applications requiring certified automotive reliability and integrated RF filtering. Consider the 40-QFN package size for space-constrained PCB layouts. Evaluate the power consumption specifications against system battery constraints. Ensure the host processor can handle the digital interface protocols efficiently. Compare performance metrics with other Si476x variants if broader frequency coverage or different interface options are needed.

RF Receivers Part Context

This part belongs to the Si476x family of single-chip radio receivers. The family offers various configurations for different market segments, including consumer and automotive. The SI4763 variant specifically targets high-performance AM/FM reception. Other members may differ in supported bands, interface types, or package styles.
