DAC38J84: DAC38J84EVM + TSW14J10EVM + ZC706 issue
Part Number: DAC38J84
i am developing a FPGA based arbitrary waveform generator, have the system components (DAC38J84EVM + TSW14J10EVM + ZC706).
i have made the connection and tried the use of HSDC pro +DAC3XJ8X GUI and configured and tested the generation of tone successfully.
Now my question is, i would like to use Vivado system design software suit for arbitrary waveform generation... can you provide example project based on my system ?
if its not available can you please help me developing the vivado based project ?
any help in this regard is highly appreciated

In reply to Kang Hsia:
thanks for your suggestions
i tried using TCL script to build the project in vivado TCL console,
the problem is,i am currently using vivado 2018.2 and the given example on TI`s webpage support only 2016.1.
kindly suggest some solution or update the firmware version for 2018.2.
In reply to Ravikant Pandey:
thank again for prompt reply.
i have another question,
keeping this in mind, i have the same set up of hardware so
is there any solution for generating customized/ arbitrary waveforms on 4 DAC outputs of DAC38J84EVM..?
i am able to generate single or double tone using HSDC pro.
any help is appreciated
Assuming you connect the DA38J84EVM to the TSW14J56EVM, you can load custom waveforms (.csv file) through our HSDC PRO software)
You can generate your own patterns via Matlab for instance. You can create 4 columns of data, one column for each DAC.
The format for the .csv data is signed 16bit integer (i.e. -32768 being most negative, and +32767 being most positive)
The TSW14J56EVM user's guide discusses the memory depth supported on the DDR bus
thanks for your suggestions
i am using HSDC PRO software to generate custom waveforms,
now my question is how to set maximum sample rate of 2.5 GSPS at all four DAC of DA38J84EVM .
because i have to generate 80 MHz wave forms and i want to use maximum sampling capability of DA38J8EVM .
please suggest the setting in DAC3XJ8X GUI to achieve 2.5 GSPS.
Any help is appreciated.
Pretty much every mode in the DAC38J84 can support your need. You will need to look at the max bandwidth supported
Afterwards, it is a matter of the lane rate and the number of lanes you have available on your FPGA. This is your application/system requirement, so we at TI cannot determine this for you.
thanks for your suggestions again.
i am trying to operate DAC38J84 at different frequency but i can only operate it in LMF-442 configuration,
please suggest me the setting for LMF_841.
i have tried doing it according to the table recommended by you but no response at output.
for example my DAC3XJ8X setup is as follows, what else i need to do..?
also, please suggest the LMK04828 clock output setup.
