• 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.

  • RE: AD9520-1 BCPZ

    Dear ,

    I can't tell from your email which problem you're having. Are you able to write and read registers? If so, then do you have a programming sequence problem?

    When debugging a serial port, it's far easier to look at the serial…

  • AD9520-1 BCPZ  

    Hi, I am using AD9520-1 BCPZ  IC for getting 12 , 250 MHz differential clocks. In this case I have left open the pin no. 63 and 64 i.e. REF1 and REF 2 and giving an differential input clock of 100 MHz at pin no. 13  & 14. Loop filter input is coming from…

  • AD9520-1 config settings


            We are using a  AD9520-1 , in two modes

    1) In mode 0 it uses internal VCO which generates 2.52 Ghz, VCO divider with division value 6, so the output frequency is 420Mhz.

       Q.) can i bypass every divider except the VCO divider?

    2) In mode 1 it…

  • 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…

  • 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…

  • AD9520-1 Eval Board - layout files available?

    Are the PCB layout files for the AD9520-1 Evaluation Board available? I am starting to layout a board with an AD9520.  Viewing  a .pdf of the existing evaluation board gerber files would be helpful... Thanks.

  • 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 ?

  • 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…
