• AD9430: Power grounds

    I am going to use the AD9430 device in our design but there is a bit of
    confusion on the power grounds. In your data sheet page 8, there is a note at
    the bottom of the page which says that The AGND and DRGND should be tied
    togather to…
  • AD9430: Unstable output

    I am using a AD9430 at 176MHz and the output does not look stable using LVCMOS
    mode (parallel).
    I have heard there may be issues regarding the LVCMOS output at high speeds.
    Please can you advise if this is the case?

     

    Any high speed…
  • AD9430: Data to DCO skew

    AD9430 datasheet Rev D page 8 of 44. max Data to DCO skew states 0.8ns. however
    tpdmax-tcpdmax = 4.3-3.8 = 0.5ns not 0.8ns?
    and no minimum stated for tpd.

     

    The skew specification is the difference in propagation delay, which is
    typically…
  • AD9430: Grounding strategy

    Should I use separate ground planes for digital- and analog ground in the PCB
    for AD9430? If so, is it enough to have separate gnds on the component layer
    gnd and let the inductance of the ground vias do the filtering or should all
    gnd…

  • RE: Can AD8306 be used as an AGC amplifier

    Hi, 

      Thank you very much for receiving your reply. 

      I want to do a receiving device.My input modulated signal(BPSK) range is -62dBm~-1dBm, and my frequency range of transmission is 20M~50M.My plan is that the signal goes through AD8306 to the AD9430 chip…

  • ADC的误差

    大家好!   

         最近看了《ADI模数转换器应用笔记,第一册》里面的AN-282:采样数据系统基本原理一节,里面讲了很多有关有效位数,噪声方面的内容,但我在实际的电路中发现,影响AD精度的原因主要是参考源和采样保持,如果选的参考源很好的话AD精度就会提高,外置的采样保持器往往比AD内部的采样保持器要好。

         我的问题是:ADC的所有误差都有哪些?有没有这种讲所有误差并且有公式的资料没?我想计算下,再和实际的电路结果对比下,看看哪里可以改进。谢谢各位大牛!

  • RE: AD9243的接地问题

    为了获得最佳的性能,建议你按照数据手册里推荐的评估板来设计PCB,对于高速ADC的布线的相关问题,建议你可以参考附件。
