ADC12J4000EVM: Not working for 1G but working for 1.6G sampling rate

Part Number: ADC12J4000EVM
Other Parts Discussed in Thread: ADC12J4000

Hi All,

This is in reference to a thread asked before by Francesco Raffaelli (https://e2e.ti.com/support/data-converters-group/data-converters/f/data-converters-forum/838036/tsw14j56evm-data-converters-forum?keyMatch=FRANCESCO+ADC12J1600) where while using AD12J4000 with TSW14J56EVM Rev E, and their respective GUI's, when we take the sampling rate of ADC as 1.6 G in the GUI, the process works and I am able to acquire data. However when we select the sampling rate of 1G, we receive the error as detailed in the screenshot. According to the solution provided in the thread, we have tried to use the new .ini file for 1G, however the error still persists. It works for 1.6G but not for 1G. Is it that we need some other changes to the .ini file to make this work? The new .ini file is present in the solution provided in the attached thread.

Thanks for your help and looking forward to your response.

Thanks and regards,

Vaibhav Jain.

  • Hi Vaibhav,

    What is the JMODE you are trying to use when capturing data at 1GSPS?

  • Vaibhav,

    There is an error in the ini file used by HSD Pro GUI. Please place the attached file in the following directory on your PC:

    C:\ Program files(x86) \ Texas Instruments \ High Speed Data Converter Pro \ 14J56revD Details \ ADC files

    When using HSDC Pro with the setup above, select the ini file called "ADC12J4000_BYPASS_1G".

    Regards,

    Jim
