• AD9121-M5372-EBZ schematic

    Hi all,

    One of our customer () trying to bring up the AD9121-M5372-EBZ board using a ZedBoard and an AD-DAC-FMC-ADP.

    Current only just a few data lines of the interface seems to be active, we are expecting some pin mapping issues. Our problem is…

  • AD9121 LVDS RECEIVER INPUTS data, DCI, FRAME inputs

    Hi all,

    Are the AD9121 LVDS RECEIVER INPUTS (data, DCI, FRAME inputs) Self-biased input ?,
    and both dc-coupled and ac-coupled available ?

    Is the input circuit different from the data/ DCI/ FRAME and DACCLK/REFCLK ?

    Best regards,
    sss

  • How to fix communication with AD9121 based on FMCOMMS1 Reference Design?

    I’m using the AD9121-M5372-EBZ evaluation board connected by FMC with a ZedBoard. First of all I modify HDL reference design (ADFMCOMMS1) by deleting the ADC IP blocks from block design and change pinout on FMC Connector. The differences between both…

    Hi, 

     You can use 'spi controller'  to access the AD9516 control.    

     The DAC Software Suite is included on the Evaluation Board CD, or can be downloaded from the DPG web site at https://wiki.analog.com/resources/eval/dpg/dacsoftwaresuite. This will…

  • RE: AD9781 BIST

    I think you need to use unsigned binary when using the  bist feature.  The AD9781 is not an easy interface when operating above 200MSPS data rate. we usually reccomend our AD9121 which is in the same package but has a more robust interface. it also has…

  • RE: AD9783 FPGA Reference Design

    Hello Rukawa,

    The FMCOMMS1-EVB reference design uses the the recommended upgrade to the AD9783, the AD9121 (also supports the AD9122). This comes as part of a full-stack reference design that:

    • Includes schematics, layout, BOM, Gerber files, HDL, Linu…
  • RE: AD9781 BIST

    Yes we willl either add this in some errata or update the datasheet ? We are also steering customers to our newer part AD9122/AD9121 that have source Synchronous LVDS interface and don't require a table to be built to determine

    delay parameters.…
