5.1. Configuring the Si47xx as an FM Transmitter Using Analog Audio Input
This mode configures the Si47xx to receive analog audio input at pins 15 and 16 (LIN and RIN). The user has the
ability to provide analog audio from RCA In connector (J7) or Line In (J19). Set jumpers J5 and J13 accordingly.
Figure 35 shows the configuration setting for analog audio input. Configure the desired parameters in the
initialization screen and then click Initialize. A new window displaying "Initializing FM Transmitter" will appear.
