ADC3683EVM: ADC data format

Part Number: ADC3683EVM
Other Parts Discussed in Thread: ADC3683, , ADC3663

Dear Sirs,

I am using ADC3683EVM. I need to run this ADC in the 16-bit mode. Data catcher TSW1400 supports ADC3683_2W_16bit for real signal processing but complex processing (with NCO) is only in 18-bit format available. May I use config file "ADC3663_2W_16bit_complex" also for ADC3683EVM? Or is it possible to edit INI file for e.g. "ADC3683_2W_18bit_complex.INI"? Do you have instructions what shall I change in the INI file?

    Viktor,

    Which version of HSDC Pro are you using where you do not have the ADC3683_2W_18bit_Complex.ini file present?

    In the meantime, please use attached: https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/73/ADC3683_5F00_2W_5F00_18bit_5F00_Complex.ini

    Place this into the HSDC Pro directory under the following:

    [relative path] \High Speed Data Converter Pro\1400 Details\ADC files

    Regards, Chase

    Hello,

    Today I have checked the version of HSDC Pro, I got the message, I am using the latest version. If you want I can attach exact version number, but simply to say it is the latest version from your web.

    This INI file is present in mentioned folder, it is OK. I want to say something else, I want to create e.g. a copy of this file (optionally rename it to ADC3663_2W_16bit_complex) and edit it such way, that it sends 16-bit complex data into TSW1400

    Hi Viktor,

    The "ADC3663_2W_16bit_complex.ini" should work. I've also attached a configuration file with a name that matches your device.

    Best regards,

    Drew
