• Difference between AD9520-1 and AD9520-5

    Hi all,

    I have an AD9520-5/PCBZ and need one more. So I tried searching for it on digikey, newark and mouser, but couldn't find it. Therefore, I am considering AD9520-1/PCBZ instead.

    My question is,

    1. Difference between AD9520-5 and AD9520-1…

  • 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

    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…

  • Programing ad9520-1 through SPI

    Hello Team ADI,

    I want to program AD9520-1 through my on board controller. can you please suggest me the CLK POL, CLK PHASE and the SPI frame format for programing the PLL?

    I have tried with the eval software it is working well.

    Thanks and Regards,

  • 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…

  • AD9520-1 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…
  • 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.

  • 使用AD9520-1的开发板,当执行vco校准,并且update后,从output没有信号输出了

    AD9520开发板,从ref1送入10MHz信号作为参考,并进行相关设置后,在output0端口能看到送出的80MHz信号,但在进行VCO的校准后,在update,发现output0没有信号送出了,只有进行reset(恢复到初始状态),才又有信号送出?这是为什么?

  • What is the maximum jitter of the output clock of the AD9520-1? I only see the typical values in the manual. It is the fs level. Can it be so good in reality?
