FM RDS PnP radio receiver

This paper describes development of a radio receiver that was designed as a personal computer (PC) plug-and-play peripheral device. The radio is capable of receiving FM signals in a standard FM band of 87.5 MHz to 108.0 MHz. Sound output is provided as a line output and a headphones output. All circuits of the radio receiver are controlled using Microchip PIC16F873 microcontroller which communicates with the PC using Universal Serial Bus (USB). RDS data is captured from Microtune 1390EHC tuner and send to the PC where it is decoded and presented to the user. USB also provides power supply to the radio receiver.
