Default Configuration

Figure 2-2. EVM and External Equipment Connections

The factory default configuration for the DEM-DAI3793A/3794A EVM is listed below.

Motherboard:

∙CN101, CN102: Connect dc power supply positive lead (+) to CN101 and negative lead (–) to CN102

∙SW301: Set Opt or Coax output for the proper cable connection

Daughter Card #1 (DEM-PCM3793RHB-A):

∙JP14, JP15, JP16, JP17, and JP19: these jumper pins should not be used

∙For other jumper settings, please refer to the chapter, Switches and Connectors.

Daughter Card #2 (DEM-TRVC/LPC):

∙SW001: Set Opt or Coax for S/PDIF input to DIR:LC89052T

∙SW002: Set to silkscreen SW002 RESET side (releasing reset)

∙SW003: Set X’tal to use onboard crystal oscillator

There is no need to change the setting of the shorting plugs for basic operation. Jumper settings strongly depend on the audio interface.
