Si471x-EVB
18 Preliminary Rev. 0.4
5.3. Configuring the Si471x to Receive Digital Input by Using Digital Source (SPDIF)
This mode configures the Si471x 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.
Please refer to Figure 24, “SPDIF Property Window,” on page 26 to control the SPDIF translator.
Notes: - Please set jumper J41, J44, and J45 according to Figure 19 to properly operate in digital mode.
- The Si471x requires the digital audio signal to be present when initializing the part. Therefore, please
connect the SPDIF IN signal prior to initializing the part.
