• RE: AD9520-5 PLL

    Dear VDPavel,

    First, the evaluation software is a handy tool for configuring the part:


    You're using the -5, which is the same as the other versions, other than the internal…

  • RE: Difference between AD9520-1 and AD9520-5

    From a performance perspective, using the AD9520-1 eval kit will be exactly the same if you either bypass the VCO, or replace the AD9520-1 on the EB with an AD9520-5.

  • ADIsimCLK ver1.7 bug? @AD9520-x

    Hi all,

    Our customer had simulated the AD9520-x w/ using the ADIsimCLK1.7.
    With the following the questions, the limited functions are bug ? or default setting ?

    The limited functions are only on ADIsimCLK1.7, not on the each devices ?

  • ADIsimCLK with AD9520-5 for Clock Distribution only?


    I want to simulate a loop filter for the AD9520-5 using an external VCO in ADIsimCLK.

    For the AD9520-5 there is only a configuration option for clock distribution with disabled PLL (no loop filter, no external VCO).

    Can I instead select another…

  • RE: AD9520 (and equivalent) driven with TCXO

    Hi Alon,

    The AD9520 can be driven with a TXCO with either single ended or differential outputs.  The AD9520 provides a self biased receiver so most differential inputs can simply be ac coupled.  Please refer to the PLL reference inputs section of the AD9520…

  • RE: AD9520/22 Evaluation Board

    Hello Paul,

    I'm trying to connect AD9520/PSBZ (rev B), AD9520-3 to 64-bit window 7. I'm not sure if AD9520-3 and AD9520/22 are using the same software. Is there any new solution to this problem rather than install 32-bit window XP on virtual machine…

  • AD9520-1 automatic reference switchover


    I'm using the AD9520-1. I want to use the automatic reference switchover.

    REF1 pin = 10MHz system clock.  DC-Coupled

    REF2 pin = 10MHz local oscillator. DC-Coupled

    When I fix the AD9520 to the REF1 pin, it runs fine. When I fix the AD9520 to…

  • RE: Single Ended Output

    Hello Kyle,

    Thank you very much for your reply.  AD9520 seems like a better choice for me since I want to have an integrated VCO.  I will be using the AD9520 evaluation board along with a highly stable single-eneded 10MHz reference clock to drive 8 DDS…

  • RE: USB connection on AD9522 evaluation board

    Dear JH,

    > Please help me how to download the "AD9520/22 Eval Board (32-bit only)" file.

    It's not a separate file.

    You need to download and install the programmer .EXE file. When you run it, you'll be able to select "AD9520/22 Eval…
