5.2. Configuring the Si47xx as an FM Transmitter Using Digital Audio with Analog Audio
Source
This mode configures the Si47xx to receive digital audio input at pins 13 and 14 (DIN and DFS), but the user still
provides an analog audio source to the EVB. It is useful for a user who wants to test digital input on the Si47xx but
does not have a digital audio source. The analog audio source is converted to digital audio through the CODEC,
which can be configured to output various digital audio formats. Refer to Figure 41, “CODEC Settings Property
Window,” on page 49 to control the CODEC. Configure the desired parameters in the initialization screen and then
click Initialize. A new window displaying "Initializing FM Transmitter" will appear.
