2. Overview

This manual describes the operation of the Silicon Labs Si4820/24-DEMO board Rev1.0, Sep 02, 2011. The

Silicon Laboratories Si4820/24-DEMO board is designed with the 24-pin SSOP packaged Si4820/24 chip, the

revolutionary single chip AM/FM/SW receiver that integrates everything from antenna input to audio output and

allows use of common and economical potentiometers to do the frequency tuning. It provides a complete portable

analog tune analog display AM/FM/SW radio design. The Si4820/24-DEMO is designed with 1-layer PCB, allowing

the lowest cost without sacrificing the RF performance. The demo board works with two AAA batteries and working

voltage down to 2.0 V.
