AD9517-0 Evaluation board to drive a prototype board populated with an AD9517-0

Hi everyone,

I am trying to use a "AD9517/PCBZ (Rev B)" evaluation board to drive an AD9517-0 installed in another board designed by us.

The intention is to use the "AD9516/17/18 Evaluation Software, Version 1.1.0" to control/program the AD9517-0 mounted in our board. To do that, we removed the evaluation board AD9517-0 and wire the signals from connector P1 to our board.


Who can I be sure that the communication with the AD9517-0 is correct?

Is it any thing that prevents this setup to work?

Any advise will be really appreciated.

Best regards

GuiX

    Hello GuiX,

    > I realize that to resolder the chip in the "AD9517/PCBZ (Rev B)" evaluation board is not so easy for me, so I am wondering if it is possible to use the evaluation board and software, with out removing the evaluation board AD9517-0, to control/program the AD9517-0 mounted in our board.

    Yes. In fact, I recommend not removing the AD9517-0.

    > and I do not know if the evaluation software needs them.

    No. Those pins are for your benefit. It is possible to read the status of the AD9517 on your board using the registers. That said, if you don't connect STATUS, LD, REFMON, the the LEDs on the eval board corresponding to those signals will not apply to the part on your board.

    > 1.- Will the evaluation software work with our board connecting it just in the SPI bus

    > and cutting the Evaluation board CSB signal?

    Yes.

    > 2.- If the evaluation software needs the rest of the signals, is it possible to connect

    > out board to them with out damaging the AD9517-0 chips (evaluation board one and our board one)?

    It's possible to make the same changes to STATUS, REFMON, and LD as you did for the serial port, but in my opinion, it's not worth it.

  • Hello Paul,

    Thank you for your support.

    It works connecting the boards as you suggested.

    Thanks again

    Regards

  • Hi Paul:

    I am working again with the board. I have something that I can not explain. When I start the program I have this message:

    I click the window and seems that the software works fine. I do not understand why the software can not detect the AD9517. Any clue?
