1. Overview
The Silicon Laboratories Si4312-DEMO board provides a complete OOK radio design with numerous selectable
features that demonstrate the capabilities of the Silicon Laboratories Si4312 OOK receiver. The Si4312-DEMO
board can be configured to receive OOK data from an SMA connector or wirelessly with an on-board printed circuit
board (PCB) antenna. The demodulated output data from the Si4312-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.
2. Features
Single chip OOK receiver
Selectable 315/433.92 MHz carrier frequency
Selectable data rate, threshold hold time
3. Description
Figures 1 and 2 show the physical layout of the board with key components indicated.
