ADS58J89EVM: Unable to use software trigger with ADS56J89EVM when paired with TSW14J56

Part Number: ADS58J89EVM

Hi,

I have been having difficulty trying to get the software trigger to function on the TSW14J56 when paired with a ADS56J89EVM.  I have successfully used the same TSW14j56EVM with software trigger (Trig Out A to Trig In) with a ADC32RF45EVM.  I know that the trigger out signal is present as I have observed it with  a o-scope and seen it work AFTER using it with the ADS56J89EVM.

Please advise.

Kind Regards,

Matthew

    Hi Mathew,

    I am looking into this. Does normal capture, without using the software trigger work for you?

    Thanks,
    Eben.

    Hi Eben,

    Normal capture works without the software trigger.

    HI Eben,

    I was wondering if you have been able to look into this issue any further? I have been using the system described above with the ADC32RF45 and successfully used the software trigger many times. It is only when I mate the TSW14J56 with the ADS58J89 that it doesn't appear to be working. The PCB for the ADS58J89EVM is Rev C and the PCB rev of the TSW14J56EVM is E. You had provided a file for me to use with the J89 in another thred. Might these be related?

    Hi Matthew,

    You will need a different firmware to be able to use software trigger for this device. Here is a link to download the firmware:
    txn.box.com/.../qu9thcp8nqz1x1q7i636289zllp882g0

    You also need to do the following:

    1) Edit the Interface name in the targeted Ini file to point to the new firmware ‘TSW14J56REVD_RX_ALT_SYNC_LVDS_AC_DC_GAIN_FW’
    ADC Ini Files path are available in the HSDC Pro installed path: C:\Program Files (x86)\Texas Instruments\High Speed Data Converter
    Pro\14J56revD Details\ADC files
    2) Copy the downloaded firmware to Firmware folder under 14J56revD Details path of HSDC Pro
    C:\Program Files (x86)\Texas Instruments\High Speed Data Converter Pro\14J56revD Details\Firmware
    3) Copy the IID Lookup table csv file you downloaded and replace the one in HSDC Pro installed path
    C:\Program Files (x86)\Texas Instruments\High Speed Data Converter Pro\14J56revD Details

    Thanks,
    Eben.

    Hi Eben,

    Sorry for delay. I've been traveling for the last week. I tried using the link provided but it states that it has been removed or is unavailable.
