TLV320ADC3101EVM in windows 7 through xp virtual machine

Other Parts Discussed in Thread: TLV320ADC3101, TLV320ADC3001

Hi, I am trying to run the TLV320ADC3101 eval board (with the USB-MODEVM) using the ADC3101 CS software. I am aware that there are no drivers for windows 7, so I created an XP virtual machine, and have been following the steps outlined in the user's guide to set it up. According to that windows should automatically find the drivers. However, I am unable to connect to the board. Any help would be much appreciated!

Thanks

    Hi Matt,

    The software should be compatible if you right click the CS shortcut and select Properties > Windows XP SP3 compatibility mode.

    On the other hand, the firmware should be compatible if it is V2.03 or above. Follow the steps in Tools > EEPROM Writer panel of ADC3101 CS to check if you have the right firmware version. Also check your jumper settings as well makng sure they match the EVM User's Guide.

    Regards,

    Thanks for the reply J. It seems that it is an issue with the EEPROM driver. I have been following the steps in "TLV320ADC3101-K Setup and Installation". I checked that the jumpers and switches are in the default positions, when I connect the USB-MODEVM to my computer,  D3, D4, D5, and D7 light up (D5 is red, rest are green). The windows drivers installed correctly (in my XP virtual machine), but when I connect the EVM, D2 does not light up. 

    I have tried following the steps in the EEPROM Writer panel of ADC3101 CS to install the firmware, but I am getting errors. 

    Another unrelated question, was the noise plot in figure 7 measured in a 20 Hz to 20 kHz bandwidth?

    After doing some testing today, I determined that the TAS1020B USB Streaming Controller on the EVM is not outputting a clock signal on MCLK01 (the crystal is functioning). I was not the last person to use this board, so I have no clue how it is configured.  Can this chip be configured to not output a clock signal?

    PS: I was asking about figure 7 in the TLV320ADC3001 datasheet.

    Thanks.

    Matt,

    If TAS1020 does not boot correctly, it will not output the audio clocks. If possible do the DFUTEST procedure in a WinXP machine to upgrade to V2.03 and then use with Win7.

    Figure 7 is 20kHz bandwidth, A-weighted. If you back calculate, 20*log(17uV/0.707) ~= 92dB-A, which is the SNR spec of the part.

    Regards,

    J-
