  • AD9852 Parallel Programming Timing Diagram

    Hi everyone,

    I'm working on a new experimental set up and I want to use AD9852 as a precise synthesizer.

    I would like to use parallel programming and program my DDS output frequency in single tone mode. I am in trouble understanding the schematics…

  • Powering DDS AD9852 Evaluation Board ???

    Hello,
    In DDS AD9852 Datasheet it is mentioned that in order to power up evaluation board;

    3.3V Vcc, 3.3V DVDD and 3.3V AVDD are required with a common ground.

    On Analog Devices website it is also mentioned in feedback section that a single 3.3V supply…

  • Question about AD9852 pulsed FM generation

    The data sheet on page 24 has the following (the italics and bold are mine) :

    "Alternatively, the CLR ACC2 control bit (Register Address 1F hex) is available to clear both the frequency accumulator (ACC1) and the phase accumulator (ACC2). When this bit…

  • RE: Programming DDS AD9913 &/or AD9852

    Hi Mars,

    Thanks for the reply. I have two other questions. The first one is about if i could use the memory with the AD9852. Then i get it from the reply that using the memory limits the clock frequency of the DDS. For my application i have to use an…

  • Can AD9852 tolerate 5V digital pulses?

    I want to program my AD9852 evaluation board with my DAQ which outputs 5Volts TTL pulses. Will the board tolerate 5V digital pulses?

  • Crystal Oscillator on AD9852 eval board

    Hello,

    Is it necessary to solder the crystal oscillator to the Evaluation board for it to work properly?  My AD9852 Eval board was working fine with an external signal generator applied to J25, but I needed to switch to a crystal oscillator.  I inserted…
