• RE: AD9287 interface (Xilinx Artix7)

    Hi Eren,

    Thank you for trying the AD9287. Would it help you to look at the FPGA source code that we use to capture data from the AD9287? This code is written for Xilinx Virtex4.

    If you would like to look at this code, please let me know and I will email…

  • RE: AD9287 Dataout frequency not right

    Hi Xiawen,

    Thank you for using the AD9287.

    I agree with what you state from the AD9287 datasheet timing diagram.

    Would you please double-check the signals you are probing? I believe it is impossible for FCO frequency to be greater than DCO frequency,…

  • RE: AD9287 signals after initialization

    Hi,

    First of all, special thanks for your close interest.

    Yes , it was related to AD9287. I had a chance to look at the code that you sent but I could not figure out why SPI_control module is not included to top module. Because I did not write the code…

  • RE: AD9287 clock derived from an FPGA - issues ?

    Hi,

    AD9287 stops operating if the clock signal is removed. It should start working again after a clock input is provided. I recommend issuing a soft reset to the AD9287 through SPI after clock is restored if you are experiencing problem with the ADC…

  • RE: Do you have a good idea for connection AD9287-100EBZ?

    Hi Kaos,

    Thank you for working with the AD9287 customer.

    You already mentioned the CVT-ADC-FMC-INTPZB. This is what came to mind when I saw your question. I believe that CVT-ADC-FMC-INTPZB takes the AD9287 outputs to the appropriate FMC connector pins…

  • RE: Do you have a good idea for connecting AD9287-100EBZ

    Thank you for your comment Rejeesh.

    But on another removed sled your Doug posted the good idea.

    Do you have a good idea for connection AD9287-100EBZ?

    For the time being, I will report above idea to our customer.

    Thanks Kaos

  • [AD9287eval board] how to change input drive for DC signal?

    Hello,

    The customer is using AD9287 EVM.

    They would like to measure the signal that mixed DC. But EVM has capacitor for rejecting DC.

    Is there any way to modify EVM input stage for accept DC level signal?

    Thank you for your help as always.

    Best regards…

  • AD9287输出数据bit速率和位时钟对不上问题求助

    我做了一个AD9287的采样,最近在做好之后,发现数据输出速率和随路时钟DCO和FCO对不上,现象表现为,我采样时钟用的是10Mhz,设置全部是默认设置,那么根据手册,一个采样点生成8bit数据,输出的数据速率应该是采样速率的4倍=40Mhz,数据输出速率也就应该等于DCO=40Mhz,帧时钟FCO等于采样速率10Mhz。我在采样的时候用示波器测量发现,DCO和FCO都是正常输出的,分别是40M和10M,而我的数据输出速率却也是10Mhz,这个事情不知道是什么问题?下图依次是DCO、FCO、采样时钟…
