• EVAL-AD9956 to generate 1kHz sine signal from 1MHz ref_in

    Question about EVAL-AD9956 and AD9956

    What is the minimum clock frequency  to REFCLK(AD9956) or J1(DUT RF_IN)?

     Is it possible to generate 1kHz sine signal at J7  from 1MHz clock into J1(DUT_RF_IN)?

    Is it possible to generate 1kHz sine signal at DACOUT…

  • RE: AD9540 Users Manual

    There is no user guide for AD9540 Eval board. We suggests that the AD9956 user guide might be helpful as AD9540 is a derivative of AD9956.

  • Using AD9956 as a waveform generator

    Hi everyone,

    I have a question about AD9956.Can i use AD9956 as a waveform generator.

    Best Regards.

  • RE: Can AD9956 generate fine-tuned sine output and perform a sweep in frequency bands above >400MHz?

    Hi,

    As a response to your questions:

    1. The AD9956 alone can output frequency sweeps up to 200MHz.

    2. & 3. An external VCO is needed for frequency outputs up to 2.7GHz. Check out these threads:

    If I don’t want to use the PLL in the AD9956, how should I terminate the unuse pins? PLLREF/PLLOSC

  • AD9956

    For my AD9956-VCO/PCBZ eval board, I installed AD9956Setup2.0.0.0-FullInstall.exe downloaded from analog.com on a PC running Windows XP. Attaching the eval board USB connector to the PC prompted the PC to search for but fail to find any suitable USB driver…

  • RE: AD9956 Frequency tuning word delivery

    Sorry, my bad, for assuming familiarity with SPI. SPI is a Serial Peripheral Interface. It is how you program the part via a micro-controller, FPGA, etc. The AD9956 datasheet has an entire section dedicated to the SPI port.

    It sounds like you are not…

  • RE: AD9540 EVAL not detected

    Hi,

    I just checked and the AD9540 software has not been updated for use with 64-bit operating systems. Fortunately, the AD9956 uses essentially the same software which will allow you to configure the AD9540 evaluation board. In order to do this, you…

  • Wat is AD9956 frequency hopping time ?

    hi

    I want to use AD9956 for an application where frequency hopping time is 110 micro sec. Im not sure will AD9956 provide me this hopping time or not between almost 16 various frequencies in a bandwidth of 200MHz.
