SI4735-D60-GM

RF Receivers Overview

The SI4735-D60-GM is a single-chip AM/FM/SW/LW radio receiver manufactured by Skyworks Solutions Inc. It operates within a supply voltage range of 2.7V to 5.5V and supports frequency bands including 153kHz to 279kHz, 520kHz to 1.71MHz, 2.3MHz to 26.1MHz, and 64MHz to 108MHz. The device features an integrated RSSI and utilizes a 20-QFN (3x3) surface-mount package. It draws approximately 10.5mA during reception and functions across a temperature range of -20°C to 85°C.

RF Receivers Feature Summary

• Integrates AM, FM, Shortwave, and Longwave radio reception capabilities into a single silicon solution.
• Includes Received Signal Strength Indicator (RSSI) functionality for signal monitoring.
• Supports standard I2C interface protocols for digital control and data exchange.

RF Receivers Applications

• Portable battery-powered radios
• Automotive infotainment systems
• General purpose audio receivers

RF Receivers Procurement Notes

Verify the specific suffix 'GM' corresponds to the tape-and-reel or tray packaging variant required for your assembly process, as packaging options may vary within the D60 series. Confirm that the 20-QFN footprint matches your PCB design guidelines. Ensure compatibility with the 2.7V to 5.5V power supply rails intended for your application environment before finalizing procurement orders.

RF Receivers Selection Notes

Select this component when multi-band coverage including LW and SW is required alongside standard AM/FM reception. The low current consumption makes it suitable for portable designs. Verify that the 20-QFN package dimensions fit within the available board space constraints. Consider the operating temperature range limits if the deployment environment exceeds standard commercial specifications.

RF Receivers Part Context

This part belongs to the Si473x family of single-chip radio tuners designed for high integration and low power consumption. It serves as a direct replacement for older C40 variants in existing designs, offering updated manufacturing processes while maintaining pin compatibility and functional equivalence for AM/FM/SW/LW applications.

RF Receivers Replacement Considerations

The SI4735-C40-GM is a confirmed obsolete substitute for this model. Designers transitioning from the C40 variant should verify that the D60 series meets all thermal and electrical requirements of the original design without requiring schematic modifications.
