Part Number: TSW14J10EVM
Other Parts Discussed in Thread: DAC38J84EVM, , DAC37J84


Do i need TSW14J10EVM board for interfacing with ADS42JBxxEVM / DAC38J84EVM ?

Can i connect ADS42JBxxEVM / DAC38J84EVM board directly with KC705. What are the advantages and disadvantages using TSW14J10EVM.


  • Hi Avinash,

    I would suggest that you look at this thread

    You can connect the ADC and DAC EVMs directly to the KCU705, but using the TSW14J10EVM allows for more of a turn key experience to evaluate the ADC and DAC. Please see the TSW14J10EVM User's Guide for more details. The KC705 has 4 data lanes routed, so you won't be able to use 8 lane modes for the DAC38J84EVM.

    Best Regards,


  • Hi Dan,

    Thanks for reply. 

    It will be helpful if i get inputs on following points.

    1. I am not sure for my requirement 4 or 8 serdes lanes are required using DAC37J84 

    Number of DAC channel = 4

    Sample rate for each DAC channel = 200 MSPS

    Converter resolution = 14 bit

    Interpolation = 1

    as per data sheet i think following setting can be used, please confirm


    2. I am planning to buy DAC3xJ8xEVM, ADS42JBxxEVM and TSW14J10 FMC-USB Interposer Card

         Does TI provide FPGA reference design for KC-705 board



  • Hi Avinash,

    The KC-705 will be able to support the 4 lane modes LMF_442 (as you pointed out above) and LMF_421.There is a Xilinx/TI reference design located at the TSW14J10EVM site under "Software".

    Best Regards,
