1.All of the spurious tones move when I change input frequency from 170,3 Mhz to 169,3 MHz especially spur 130,7 Mhz to 129,7 Mhz as you can see in the pictures below:
3.Unfortunately I can not change the sampling rate by 1 MHz because I use the…
My customer tried to open the following simulation file for AD9516 through ADIsimCLK and then was required to open the following library file. Could you please help my customer to get "IDT82V3280.lib" and/or to fix the following issue?…
FMCOMMS1 used to use a AD9122 not the AD9121.
Also this board doesn't have AD9523, AD9548 clock chips, it uses the AD9516.
Why is it still probing them?
Error: -5 is EIO (I/O error) which means the drivers can't talk to the HW.
How did you connect…
Can you please clarify what you mean by the frequency shakes? How do you have the LVPECL outputs terminated into your spectrum analyzer? Can you read that the PLL is locked by monitoring the LD pin (0x0A1[5:0]=0)? The loop filter components on the…
Thank for your quick answer.
I have an other question:
I have the AD9913 to create a sweep from 5 to 80 MHz and after I would like to use the AD9516-4 to moltiply x10 my sweep to create a sweep from 50 MHz up to 800MHz.
Is that possible to do with…
Recently I make the AD9516-3 to output 1G ，250M and 200M from the REF_SEL 200MHz. I plan to connect the REF_SEL of AD9516-3 to 200M difference clock from external chip.but How do I connect the REF_SEL? The datasheet only tells me about REF_SEL…
Hello, I have some questions about AD9516-3.
When using an external VCO, how the LF pin should be ? Should the LF pin be connected to VS, GND or others ?
And could you tell me other attention when using an external VCO ?
