  • Page 7: Description

    The DEM-DAI3010 is an evaluation board for the PCM3010 (24-bit, 96-kHz ADC and 192-kHz DAC, stereo codec). This board includes not only the PCM3010 but also analog I/O terminals, analog filter circuits, and an S/PDIF digital I/O circuit that is useful for codec evaluation. S/PDIF I/O circuits consist...

    Settings and Connections for Basic Operation 1.3 Settings and Connections for Basic Operation The PCM3010 is an LSI codec containing an ADC and a DAC. Connections and settings depend on the evaluation object (ADC or DAC), and the setup should be checked carefully. Following are example settings for three typical evaluation situations.
  • Page 11: Setting Functions

    1.4 Setting Functions All functions of the devices (PCM3010, DIR1703, DIT4096) on the DEM-DAI3010 are controlled by DIP switches or header pins on this PCB. Therefore, the DEM-DAI3010 does not require a microcontroller or software to transmit data to internal function-setting registers. For specific information on any device, see the data sheet for that device.

    Setting Functions 1.4.2 Detailed Explanation of Function Setting Switches and Header Pins SW001: Switch to select S/PDIF input connector (optical/coaxial). Selection of the S/PDIF signal that is routed to the DIR1703 DIN port. SW002: Reset switch for the DIR1703 and DIT4096. Pushing this switch resets the DIR1703 and DIT4096 to the initial state.
  • Page 13 FMT1 FMT0 SW006: Switch for setting channel-status data of the DIT4096. Note that the OFF state of this switch sets a HIGH level. Channel status data can set up if needed. Moreover, it is also possible to connect a microcontroller to CN002 and to write in channel-status data with the microcontroller.
