Product Attributes

Introduction

Minimal BOM components with no manual alignment. Excellent real-world performance. China TV channels audio carrier reception in FM band. 2.0 to 3.6 V supply voltage. Wide range of ferrite loop sticks and air loop antenna support. 16-pin SOIC package. RoHS compliant. Not EN55020 compliant. Modules for consumer electronics Toys, lamps, and any application needing an AM/FM/SW radio. The Si4827 is an entry level analog-tuned digital-display digital CMOS AM/FM/SW radio receiver IC that integrates the complete receiver function from antenna input to audio output. Working with Host MCU (I²C-compatible 2-wire control interface), frequencies information can be displayed on LCD while the analog-tune features are kept. The Si4827 enhances the FM and SW band coverage, and further supports China TV channels audio reception in FM band. The superior control algorithm integrated in the Si4827 provides an easy and reliable control interface while eliminating all the manual tuned external components used in traditional solutions.
