Looking for a support on AD9522-1 input reference clock. We are using singled ended reference clock[one from FPGA, one from oscillator], with AC coupling and AD9522 internal DC offset is off.
When we probed on the REF_IN pin, there is a -0.4V offset…
My customer has used AD9522 evluation board with AD9522 evaluation software version 1.2.0.
In the case, the USB Status is 'EZSSP-0'.
Recently, the customer purchased an additional AD9522 evaluation board.
The new AD9522 EVB only works…
I designed a PCB that includes an AD9522-1 that I intend to use for clock distribution. The supporting circuitry for the AD9522-1 is basically a copy of the AD9522/PCBZ Evaluation Board (which I also use to program the AD9522-1 in my design by means…
We interest on AD9522-4 for our design, we get the AD9522/PCBZ evaluation board to check it.
my question is regarding this note from UG-077
" 1. Install the AD9522 evaluation software. Administrativeprivileges are required for installation…
Almost every five times I turn on, It happens once.
i drive clock as differential with AD9522. after fpga loaded from flash i config AD9522, and set clock to 60MHz.
if we enable the DRVDD regulator with AD9522 lock flag, and then assert digital…
I'm currently attempting to use the AD9522 Eval to clock my AD9914 Eval. I am using the internal VCO of the AD9522 Eval, but when I externally measure the output signal of my AD9522 I see a different frequency from what the evaluation GUI is telling…
Where can I find driver code for AD9522?
I tried all downloads in AD9522 page, but seems that nothing contains software source code.
I would like to confirm about unused CLK/CLK# input pin of AD9522-1.
What is the recommended state? (Open, Pul-up,,,)
I am seeing the same issue. This is a valid configuration. An easy work around is to use the AD9522-4 model and instead of a total feedback of 20, use a feedback of 16.
The model for the AD9522-4 will be an accurate representation of AD9522…
The AD9522-0 has an internal VCO frequency range of 2.53GHz - 2.95GHz. That frequency range does not support an integer divide to create 800MHz at the output. The tool is not letting you set the VCO divider by 1 because of the internal VCO…
