1. Overview
The Silicon Laboratories Si4311-DEMO board provides a complete FSK radio design with numerous selectable
features that demonstrate the capabilities of the Silicon Laboratories Si4311 FSK receiver. The Si4311-DEMO
board can be configured to receive FSK data from an SMA connector or wirelessly with an onboard printed circuit
board (PCB) antenna. The demodulated output data from the Si4311-DEMO board can be measured via an SMA
connector and/or observed with an LED and/or heard with an audio buzzer. The system is powered by a 9 V
battery or an external 3.3 V power supply.
