• AD9954: Synchronization of 16 AD9954

    1.Our design uses the two options described on datasheet page 30. I.e.
    synchronizing with SYNC_IN and SYNC_CLK signals AND a single crystal driving
    multiple (=16) AD9954s. Do you recommend using it this way?

  • AD9954: Need to generate a quadrature signal synchronized to the output of the AD9954


    I have put/found my self in a bad situation, while designing a LCRZ-meter I researched several techniques and originally I was going to use 2 ADCs precisely timed to the DDS output of the AD9954. But since the design calls for a excitation signal…

  • Is it possible to make Spectrum Analyzer by using AD9954 or EVAL-AD9954 ?

    I want to make Spectrum Analyzer to  measure conducted EMI from  power converter (AC/DC-AC/DC).

    If it is possible to make Spectrum Analyzer form AD9954 then please help me.

  • AD9954 synchronisation


    Assuming I have single ad9954 on my board and it doesn't need to be synchronized:

    1) I plan to turn off sync_clk output, what should I do with sinc_in pin?

    2) Which synchrinization mode I need to configure?

    3) I drive IO_UPDATE from async…

    I am  evaluating AD9953 chip. We have  AD9954 evaluation board for the same.


    We are tried configuring AD9954 in  different modes,

    we are not able to  configure in linear sweep mode because it requires  PS0 and PS1 pins toggling.

    There is no option to…

    I am looking for a step by step example of using the AD9954 RAM for both frequency hopping and  having trouble understanding the discussion on the use of the RAM on the data sheet.  The basic question is:  Can I use the RAM to pre-program a series of FTW…

  • AD9954 Issue

    Dear Sir/Madm,

    There are three circuit figures in the EVB of Ad9954 t, i wonder what is the difference between U7 and U8,  which include ad9954.


  • RE: ad9954

    From Google Translate:

    I want to output 47 ~ 100Hz with ad9954, but the IC will perform. If not, please recommend 14bit.


    The AD9954 can output your desired frequency sweep.

    Best regards,
