AD1937 evaluation board

Is there any way I can program a input of the eval board to an output of the eval board using the Register Window Builder Program. I would like to plug some PC audio to an input and then a speaker or headset to the output.

    Hi Tom,

    Thank you for your interest in the AD1937 codec.

    The USBi control interface and Register Window Builder program are only able to control the registers in the AD1937; the routing of clock and data on the eval board are not affected by this control path.

    I have two methods to complete a loop-through from ADC to DAC:

    1)      Connecting a coax cable from the SPDIF output to the SPDIF input; the signal at ADC pair 1 should appear at all DAC pair outputs.

    2)      Using short patch cords, connect the serial clock and data signals from the ADC output to the DAC input using the pins at HDR1.

    The routing of clock and data  through the CPLD on the board is described fully in the User Guide which is available on the AD1937 product page:

    Please let me know if this is not clear or if other questions come up.

    Best regards,

    Coleman
