I haven't found the way to set the prescaler of AD9520-5 to 1. In datasheet says that prescaler in fixed division can be set to 1, 2 or 3. But also below the "VCO/VCXO Feedback Divider N: P, A, B, R" says that P can be 2, 4, 8, 16 or 32. I have…

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…
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…
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 ?

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…
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…
Hello Sir,
I have done the programing of AD9520 clock synthesizer but I am not able to find out the way of programming the EEPROM. Kindly give me some suggestions.
Hello,
I am trying to get the Windows device drivers for the AD9520/22 Evaluation Board. I installed the AD9522EvalSetup.exe but it did not include the drivers.
I need drivers for Win XP and Win 7 64.
Thank you,

Hi,
I am using AD9520-0 clkgen, I am trying to communicate it using SPI.
I have made the following configuration:

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…
