Si471x-EVB
Preliminary Rev. 0.4 17
5.2. Configuring the Si471x to Receive Digital Input by Using Analog Source
This mode configures the Si471x to receive digital audio input at pin 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 Si471x 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. Please refer to Figure 23, “CODEC Property
Window,” on page 25 to control the CODEC.
Note: Please set jumper J41, J44, and J45 according to Figure 18 to properly operate in digital mode.
