• RE: AD9520-5 PLL

    Hi vdpavel,

         Did you also set R0x16 bit [3] = 1? This sets the B-counter to a divide by 1 state and allows the prescaler value to determine the entire N divide.

  • 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?

    Hi,

    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…

  • AD9520-1 automatic reference switchover

    Hi,

    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: ADIsimClk with Zero Delay Function

    Hi Paul,

    I just wanted to let you know that I sorted out the issue.  I was using the AD9520-5 and AD9522-5 which doesn't have an internal VCO which would cause the program to crash when i tried to use the zero delay function.  When i select any other…

  • AD9520-1 config settings

    Hi,

            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…
