• AD9737A-EBZ output capacitor

    Hi,

    AD9737A-EBZ has a capacitor(C79) in the output stage whereas AD9739A-FMC-EBZ doesn't have the capacitor. what is the use of this capacitor and is this required in Cable TV application?

  • Query about AD9737A's 3GHz Output

    Hi, there

    I am planning to design signal generation with AD9737A. The output frequency is 3GHz. I read AD9737A could output 1.25 GHz to 3.0 GHz in mix-mode.

    Could you please help guide me how I can get the output at 3GHz in the mode? such as its input…

  • AD9737A FMC board to dc couple

    hi,

    When i use AD9737A FMC board, i find out that it is just AC-couple from 5MHz to 300MHz.  However, i would like to use it by DC-couple because my band-width is from zero to 200MHz. So, how can i modify the EVAL-AD9737A-FMC-EBZ component? I wonder if…

  • AD9737A差分输出的问题

    尊敬的ADI工程师您好:

    AD9737A这款DAC芯片,datasheet上写到模拟输出差分电阻为70欧,我的需求是:输出差分对的N端接一个无源滤波电路,P端接一个无源滤波电路,每个滤波电路特征阻抗都是50欧,请问怎么阻抗匹配?

  • AD9737A这款芯片配什么时钟芯片

    AD9737A这款芯片配什么时钟芯片,datasheet里提到的ADICLK914频率到达7.5G,而AD9737A要求DACCLK输入范围1.6G—2.5G??怎么用呢?

  • RE: I am using the AD9739A-FMC-EBZ and the level translator, U1, is not correctly translating my input serial signals.  How do I fix that?

    Can you check if the enable pin of U1 - pin 10 is low.

    There are two options to talk to ad9737a - FMC SPI or PIC18F24 SPI.

  • RE: Low Latency 2.4 G sample/sec (min) DAC for wireless backhaul modem application

    Many of our high-speed DACs in that speed range use JESD204B interface which introduces more latency than LVDS. However, if you consult the HIGH-speed DAC product selection guide, you will see a few options beyond the LTC2000, such as  AD9737A, AD9739A…

  • RE: AD9739

    I do an experiment with  AD9739a-fmc-ebz-revC eval board and xilinx KC 705 FPGA platform, but when measuring the DAC output signal , I found highr harmonics .Startup initialization is similar to recommended at page 62(Data Sheet AD9737A/AD9739A).I've generated…
