This tuner circuit is a quick prototype which I build to test the RDA5807M FM radio tuner IC. RDA5807M is a single-chip tuner IC with RDS and MPX decoder, and it equipped with I 2 C interface for control. The main reason to build this prototype is to understand the behavior of this chip. The prototype version of the RDA5807M receiver. At the time of this design, the website of the RDA microelectronics is not accessible from my location. Because of this reason, I download different versions of RDA5807M datasheets from the internet. While going-through those datasheets, I observed that it comes with limited information. Finally, I decided to build this receiver to verify some of those parameters and to review the RDS functionality of the chip. I build this receiver around ATmega16A MCU. I choose this MCU because I got a few of ATmega16A MCUs in my inventory and also due to the higher number of I/O pin count. RDA5807M module. In this design, the volume is contro...
