Rev. 0.1 5/13 Copyright 2016 by Silicon Laboratories Si4844-B-DEMOSi4844-B-DEMO 2. Overview This manual describes the operation of the Silicon Labs Si4844 DEMO board Rev1.4, Mar 12, 2013. The Silicon Laboratories Si4844-DEMO board is designed with the 24-pin SSOP packaged Si4844-B 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 digital display AM/FM/SW radio design. The LCD displays the tuning information. The Si4844-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. 3. Description Figure 1 and Figure 2 shows the physical layout of the board with key components indicated. Figure 1. Si4844-DEMO Board Top Side in Time Mode 2 Rev. 0.1
