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 3 feet. |
