  • AD9856: Pin connection

    Q 

    I am investigating problems on a PCB containing an AD9856. The SDIO pin
    is driven from a 244 buffer however there appears to be contention on
    this pin.

    I am not sure whether some pins on the device are connected correctly.
    The PLL…

  • AD9856 does any pulse shaping?

    Hello everyone,

    I am doing QPSK modulations on given data using AD9856.

    I am getting modulated signal with some pulse shaping.

    I just wanted to confirm that in AD9856 is there any inbuilt functionality to generate Modulated data in some specific pulse…

  • Can you send me the AD9856 filter coefficients?

    Q 

    Can you send me the AD9856 filter coefficients?

     

    A 

    Below are the filter coefficients:

    Halfband 1:
    coefs[0] = -1;
    coefs[1] = 0;
    coefs[2] = 4;
    coefs[3] = 0;
    coefs[4] = -10;
    coefs[5] = 0;
    coefs[6] = 22;
    coefs[7] = 0;…

  • Simulation of Schematic as per provided in AD9856 datasheet in ADIsimPE?

    I wanted to simulate, Evaluation board schematic as per provided in the AD9856 datasheet.

    I am using ADIsimPE but in that, I am not getting AD9856 part details to place it. Also, I was unable to get AD8320 for the same.

    I made a hardware interface of…

  • 谁能帮忙看看AD9856的问题？要是能解决了我把代码全都贴出来给大家共享1

    不好意思写的比较长，还有图，是想让人看得明白一些。

    希望用AD9856做一个正交调制，I、Q两支路为码速率4.2966MHz的数字信息，经过AD9856正交调制之后输出为20MHz的中频信号，系统框图如下图：

    上图中的脉冲成型滤波模块以4倍采样对I、Q两路信息进行脉冲成型滤波，输出为17.1864MHz（4.2966MHz×4）的有符号数（输出字长15比特，取高12位（第3——15位）输入AD9856，最高位为符号位，满足AD9856二进制补码的输入要求）。

    写AD9856（红色框）将I、Q两支路脉冲成型后的数据按照I1…

  • RE: AD9854

    Hi, Dr. Babankumar.

    For your qeustions:

    1. Other QDUCs (quadrature digital upconverters) that we have are AD9856 and AD9857.

    2. No, it needs a Parallel port connection.

    3. I'll get back to you on this.

    4. As of today, what we have is AD9914 which…

  • RE: I can't download the software of AD9956

    I read your message. Thank you for your help.

    Let me ask you something more.

    When I used AD9852 EV board, I could use a document about instruction file(.pdf).

    AD9852 instruction file mentioned that HOW TO USE each parts of AD9852 EV board.

    For example…
