2. Overview
This user’s guide describes the operation of the Silicon Labs Si4836-DEMO board rev1.1, Nov 20, 2012. The
Silicon Laboratories Si4836-DEMO board is designed with the 16-pin SOIC packaged Si4836 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 Si4836-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.
