ADS54J69: ADS54J69IRMP Device SPI REG value generation GUI is Required

Part Number: ADS54J69

Dear Sir 

ADS54J69IRMP Device SPI Register map value generation  GUI is Required sir 

kindly provide link to download the same sir 

thank you

    The GUI can be downloaded from the ADS54J69EVM product folder on the TI website. See attached.

  • Dear Sir,

    Thank you very much  

    Can you please help with FPGA Interface for the same 

    1) Linux SPI Driver  or bare metal SPI Driver to interface with Xilinx MPSOC

    2) confused with register sets generated from GUI, datasheets says some set of registers and GUI Generates some sets 

    so little confusion 

    i would like to operate ADC at 320MHz clock for sampling and 2 lane per channel , both channel needs to be active and 

    LMFS   => F= 1 and K=1 

    please help out 

    thank you

    regards

  • Balakrishna,

    For #1, I cannot help with this.

    For #2, per the JESD204B standard, the following equations must be meet: 17 < F * K < 1024 and 1 < K < 32

    Since you will be using LMF = 422, F = 2. To meet the equations above, we normally set K = 16.

    This part can operate in either low pass or high pass mode. I am sending  configuration file for you to try that will be configured for low pass mode with K = 16.

    With a sample rate of 320MHz, the ADC output rate will be 160MHz. SYSREF = ADC data rate / (n * K), with n = whole integer.

    The maximum SYSREF frequency you can use is 160M / 16 = 10MHz.

    Give this a try.

    Regards,

    Jim
