• AD9520-1 BCPZ

    Hello Sir , I have a customized board in which We have used AD9520 IC. I have checked the IC in default mode it is alive i.e. it is giving a response of 6.25 MHz.
    I am trying to write a code through which I can write some value into the register and read…

  • 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 ?

  • 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…

  • AD9520 PLL frequency question

    Regarding the 9520-4, I want to use the 9520 to lock a signal at a far end of about 40Mhz, and come out to generate phase-dependent signals of 160M and 40M. The following figure is the design generated by ADIsimCLK software. Some questions are not clear…

  • AD9520 VCO direct mode

    Hello,

    I want to know skew value for outputs in VCO direct mode.

    There is skew value for channel dividers outputs in datasheet, but no data for outputs in VCO direct mode.

    Also want to know time delay between outputs which work in VCO direct mode…

  • AD9520 PLL lock problems

    Hi, we're encountering problems  setting up the PLL of a 9520-3 properly. As reference clock, a TCXO with  fref=20MHz is used which directly drives the PFD. The 2GHz VCO is  divided to 20MHz via a 32x-Prescaler, a B-Counter of 3 and an A-Counter  of…

    Q1:

    I want to confirm whether multiple pieces of HMC7044 can synchronize? Is the synchronous signal SYNC or RFSYNC?

    Q2:

    I have two pieces of HMC7044, how do you synchronize? Do you have a plan?
