• AD9265没有低位数据

    大家好,我设计了一版 AD9265+FPGA的采集板, AD9265的模拟与数字供电均通过磁珠与1.8V网络连接,AD9265的 DCO OR D0~D15 通过22欧姆电阻与FPGA直接连接(FPGA BANK电压也是1.8V)。 AD9265的差分时钟输入由FPGA提供(30MHz)。

    经过测量,AD9265的DCO输出是正常时钟,VREF 1.0V, VCOM 0.9V,然而对信号发生器的 100KHZ 300mVpp 进行采样并回传发现,正弦波被AD9265采样采集成了 多段台阶,也就是AD9265的大部分低位数据都是0…

  • 关于ada4930问题,翘尾现象!

    此电路参考ad9265参考设计中的CN0252中的电路(后端接的也是ad9265),ad9265输出vocm为0.9v,在图一AB两点输入高电平为2V 低电平为0v的100K脉冲信号,占空比为5%。在CD两点测得图二的信号,感觉信号自激了。但是电路完全按照参考设计来的,不知道哪里出了问题。

  • AD9265-FMC-125EBZ and 7030 PicoZed + FMC Carrier Card V2

    Hi all,

    can you please confirm me that the AD9265-FMC-125EBZ is compatible with the 7030 PicoZed + FMC Carrier Card V2.

    I'm pretty sure it is compatible with the AD9467-FMC-250EBZ. I guess should be fine also for the AD9265-FMC-125EBZ. I suppose the…

  • AD9265 BIST feature

    W're using your ADC AD9265, We like to use its BIST feature to verify data lines. PN9 is used to test it, The number sequence captured are 073C, 2E44, 121C, A3CE...the numbers are repeated every 511 count. I don't know if the numbers captured …

  • RE: ad9265 on Mini-ITX

    Lars, the design uses the zynq-spi.

    Istvan, I followed those steps, but added one last one.  We have the mini-itx 100 part and not the 045.  So After generating the project, I changed the project part to match the zc7z100 and recompiled everything.

    When…

  • RE: AD9257 Xilinx IP

    Thanks!

    I'm also curious, could the ad9265 or other HDL code in the repo be modified by simply changing the 16 bits to 14 bits throughout the code?

    The AD9265-FMC is very similar to the AD9467-FMC you can find some instructions here:
