Product Overview

The SI4730-D60-GUR is a highly integrated, low-power digital CMOS AM/FM broadcast receiver supporting global FM (64–108 MHz) and AM (520–1710 kHz) bands. Leveraging an advanced digital low-IF architecture, it eliminates the need for external manual calibration, delivering high-performance signal reception and audio processing for consumer electronics such as clock radios, mini HiFi systems, and portable radios.

Key Features

• Full Band Coverage: Supports FM (64–108 MHz) and AM (520–1710 kHz), compliant with global broadcasting standards for versatile regional use.
• Exceptional Reception: Offers 2.2 µV EMF high sensitivity (FM mode) with Automatic Frequency Control (AFC) and Automatic Gain Control (AGC) to suppress interference and enhance weak-signal reception.
• Low Power & High Integration: Requires minimal external components in a QFN package, with standby current as low as 4 µA (shutdown mode), ideal for battery-powered portable devices.
• Flexible Audio Interfaces: Supports both analog audio output (LOUT/ROUT) and digital audio output (DOUT/DFS/DCLK), compatible with I2S, left-justified, and DSP formats for seamless integration with audio systems.
• Intelligent Signal Processing: Built-in stereo decoder, soft mute, and programmable de-emphasis filter to optimize audio quality and reduce noise interference.

Technical Specifications

Typical Applications

• Clock Radios: Integrates FM/AM reception with automatic station search and precise tuning, paired with low power consumption for desk or bedside clocks, ensuring clear and stable broadcast reception.
• Mini HiFi & Docking Speakers: High sensitivity and stereo decoding enable high-quality audio reproduction, supporting digital audio output for direct connection to amplifier modules, ideal for compact audio systems.
• Portable Radios: Wide voltage range and low power draw suit battery-powered designs, with a compact package for easy integration into outdoor or mobile devices, handling complex signal environments via AGC.

Why Choose SI4730-D60-GUR？
