DAC38RF89: data sequence of FPGA

Part Number: DAC38RF89

 HELLO, I use DAC38RF89 with the mode  LMFSHd = 82380 1X,the FPGA is XC7K410T-2FFG900, NOW the link  of jesd204b is ok, but the output of 

DAC wave form is incorrect ,  so I doubt  that the sequence of the data I arranged in FPGA endding is wrong . Could you show me the correct  data sequence

of FPGA.  

  • Hi,

    You may follow the frame format of the 82380 shown on Table 25 of the datasheet.

    You will need to make sure that the starter multi-frame of your JESD204 data stream matches the starting frame of the LMFS shown below. There are pattern generator checker described in the datasheet for you to check the pattern is send correctly or not. Thank you.
