SI4730-D60-GU

RF Receivers Overview

The SI4730-D60-GU is a digital CMOS AM/FM radio receiver IC from Skyworks Solutions Inc., designed for complete tuner functionality from antenna input to digital audio output. It supports worldwide FM bands (64–108 MHz) and AM bands (520–1710 kHz). The device operates on a supply voltage of 2V to 5.5V and features a 24-SSOP surface-mount package with dimensions of 0.154 inches (3.90mm) width. It functions within an operating temperature range of -20°C to 85°C.

RF Receivers Feature Summary

• Integrates complete tuner function from antenna input to digital audio output
• Supports worldwide FM band reception from 64 MHz to 108 MHz
• Supports worldwide AM band reception from 520 kHz to 1710 kHz

RF Receivers Applications

• Portable AM/FM radio receivers
• Digital audio devices requiring integrated tuning
• Consumer electronics with space-constrained designs

RF Receivers Procurement Notes

Verify the specific suffix 'GU' corresponds to the 24-SSOP package variant when sourcing, as other suffixes like 'GM' or 'GUR' indicate different packages such as QFN or SSOP. Confirm that the required frequency coverage matches the SI4730 model, which lacks the shortwave support found in SI4734/35 variants. Ensure compatibility with the 2V to 5.5V supply voltage range for the target application design.

RF Receivers Selection Notes

Select this component for applications requiring a fully integrated digital AM/FM tuner solution. The SI4730 model is suitable for standard broadcast bands but does not include Shortwave (SW) band support; consider SI4734 or SI4735 if SW reception is necessary. The 24-SSOP package offers a compact form factor suitable for surface mount assembly. Verify power supply requirements align with the 2V minimum and 5.5V maximum operational limits.

RF Receivers Part Context

The SI4730-D60-GU belongs to the Si473x-D60 family of digital CMOS radio receivers developed by Skyworks Solutions Inc. This series integrates the entire tuner function into a single chip, simplifying design complexity for AM/FM radio applications. The D60 designation typically refers to the specific package and thermal characteristics within the product line.
