• AD9834: Operation of DDS

    When I have 10 Mhz master clock and I want to have 1 Mhz output frequency, how
    many points (time domain) will my output signal have?


    The tuning word specifies the output frequency as a fraction of the reference
    clk frequency, therefore a tuning…

  • AD9834: MSB output jitter reduction

    We would like to get a output square wave by using of AD9834.
    The MSB is output at pin 16 but the edge is jittering and the waveforms have
    been attached.
    As we know, the jitter of output is dominated by that of MCLK, but the problem
    is still…

  • AD9833: Difference between AD9833 and AD9834

    I want to use one of these two DDS chips (AD9833/AD9834) to generate a square
    wave signal of 10...90kHz from a 7.2Mhz clock. All I need is a square wave
    output. I therefore don't need the DAC running but intend to use the MSB output

  • AD9834 Single Output


    I have a quick question about the AD9834 DDS. I have designed a board that is going to become an automated test rig for a few products. It will take out a lot of hard work when testing a board. For instance, plugging in a board and it measuring voltages…

  • AD9834 B or C grade


    I have a project with AD9834BRZ used in. DDS is driven by 75 MHz. But in datasheet found 50 MHz MAX declared in ordering guide for B grade. The only differencies i found are currents of power supply and narrow band SFDR. Does it mean other dynamic…

  • AD9834 Drivers - Download problem and possible error in the oldest version


    I am having problems with the download of the latest  AD9834 drivers 

    The no-os Driver links are broken (lead to a dead end), so I tried using the older ones that does not seem to be working

    Of course I  inserted and tested the proper SPI dll's…

  • AD9834: outputing only one or two cycles not continuous waveform

    Dear AD Team,

    I have designed DDS board with AD9834. I am using Teensy 3.5 that 32 bit arm on it. I am able to output sine wave with the frequency I want. I am using 4MHz MCLK. My aim is to output frequencies between 100Hz and 2MHz.

    I have 2 question…

  • AD9834: output sin frequency is not exactly like set in Software

    Hello everyone in forum,

    I am using STM32F7 to provide the mclk(currently it is 1 MHz) and configuration via SPI to generate the sin wave from AD9834. But I found some issues, the output for 1000 Hz, 2000Hz and 10kHz are good enough, but at 500 Hz there…
