Description

This is an evaluation board for the Silicon Laboratories Si4703 FM tuner chip includes an amp and a headphone jack, and that’s everything you need to get up and running! Beyond being a simple FM radio, the Si4703 is also capable of detecting and processing both Radio Data Service (RDS) and Radio Broadcast Data Service (RBDS) information. The Si4703 even does a very good job of filtering and carrier detection. It also enables data such as the station ID and song name to be displayed to the user.

Using this board we are able to pick up multiple stations just as well as with a standard FM radio. The board breaks out all major pins and makes it easy to incorporate this great chip into your next radio project. Also, by plugging headphones into the 3.5mm audio jack, you effectively use the cable in your headphones as an antenna! Therefore, this board does not require an external antenna if using headphones or a 3.5mm audio cable longer than 90cm (3 feet)

The board provides access to SDIO and SCLK for I2C communication while RST can be used for easy resetting.

The SEN pin enables the user to change the mode of the functionality of the IC. The pins GPIO1 and GPIO2 can be used as general input/output pins, but also can be used for things like the RDS ready, seeking or tuning functions.
