  • the usage of AD9249

    hi 

    this is my first time to use AD9249 and i don't have the evaluation board .i  tried a lot  but failed , 

    i need the AD output with 14bits and 50MSPS and DDR . I only use the channel VIN+A1,VIN-A1 . So i use AD9553 output (50M LVDS) as the CLK+,CLK…

  • EVAL-AD9249 - FMC connector pinout

    I want to connect an EVAL-AD9249 to my own board with a Xilinx Zynq-7 FPGA and an FMC connector. I cannot find the pinout for the FMC connector on the AD9249 eval board with FMC connector. The schematic for the EVAL-AD9249 seems to be missing the connectors…

  • about AD9249-65EBZ REV.B.

    hello, 

    i already ask a question about AD9249-65EBZ REV.B.

    but , in www.analog.com/.../AD9249_Design_Integration.zip this link is about REV.C.

    REV.C version is connection is like this. i circled.  

    but my AD9249 is REV.B     

    it is different from REV.C. how can…

  • AD9249 - square waveform

    The input signal at B1 is a square waveform. The signal source is a function generator (50 Ohm impedance). The voltage waveform is shown with "Visual Analog"  for different frequencies.

        1MHz 1Vpp (witho…

  • AD9249-Channels not synchronous

    Hi. I use the following product: AD9249-EBZ 65. I have tested the board as described on the following page: https://wiki.analog.com/resources/eval/ad9249-65ebz. I have selected the following file: AD9249_14Bit_65MSspiR03.cfg.

    I have fed the same sin…

  • AD9249 input voltage range

    Hello ADI team.

    I have a question.  Currently, the are our adopt AD9249 / 9681 in a single-ended

    In use, the input voltage from the input range (0.4V ~ 1.4V) is barely

    When raised, the greater the number clock, that of a digital noise is.

    Because…

  • Request for AD9249 FPGA reference design

    Hello:

     Excuse me seeking help here.  I am going to work on a new project where AD9249 is used for data capture and the data are fed to Xilinx's KC705.  Would anyone please send me a copy of the AD9249 reference design of the FPGA project?  I am using…
