5.3. Configuring the Si47xx as an FM Transmitter Using Digital Audio with SPDIF Digital
Source
This mode configures the Si47xx to receive digital audio input at pin 13 and 14 (DIN and DFS) when the user has
an SPDIF digital audio source. The SPDIF source is converted to PCM digital audio by the SPDIF translator. Refer
to Figure 42, “SPDIF Settings Property Window,” on page 50 to control the SPDIF translator.
Note: The Si47xx requires the digital audio signal to be present when initializing the part. Therefore, connect the SPDIF IN
signal prior to initializing the part. SPDIF will not be supported on new EVBs as of February 14, 2011. This mode of
operation will not be available in the initialization window for those boards.
