• 关于AD9717的输出相位偏移控制（About AD9717 phase offset control）

    您好，

    Hello Ms./Mr. ，

     

    从AD9717数据表来看，有重定时器的功能可以对相位进行调整，但是只有最低90°的分辨率，远远不够我的设计要求。

    From the data sheet of AD9717,  the function of retimer can adjust the phase,  but only the minimum resolution of 90° is far from my design requirements.

  • AD9717: Pin connection

    Q 

    Please advice me how to connect "DVDD" pin, 1. to a capacitor only 2. to 3.3V
    3. do i need to activate the internal LDO or not. 4. others I'm confused since
    on top of Table 1 it's define "DVDD=3.3V" in "absotute max" table DVDD…

  • AD9717 eval board

    Hi, I have an AD9717 eval board. The documentation is difficult to sort out. First, the documentation on the web site is REV A and does not seem to relate to the REV C hardware I have. The information on the CD which came with the eval board, which is…

  • AD9717 power supply

    Hello,

    Does AD9717 support next power supply configuration: AVDD = 3.3V, CVDD = 3.3V, DVDD = 1.8V, DVDDIO = 1.8V?

    Does "Strap DVDD to DVDDIO at 1.8 V" mean "connect DVDD and DVDDIO pins together on the PCB if DVDD = 1.8V and DVDDIO = 1.…

  • Power supply configuration for AD9717

    1) Does the AD9717 support the power supply configuration: AVDD = 3.3V, CVDD = 3.3V, DVDD = 1.8V, DVDDIO = 1.8V?

    2) What is the absolute maximum ratings for DCLKIO?


  • About AD9717 Phase Offset Control

    Hello Ms./Mr. ，

    From the data sheet of AD9717,  the function of retimer can adjust the phase,  but only the minimum resolution of 90° is far from my design requirements.

    I wonder if AD9717 has phase control function? Similar to the phase control word…

  • Sinusoidal Wave using AD9717

    Is it possible to create sinusoidal wave using AD9717? If so, how? The DPG Palette on the evaluation board software has an example simple sine generator, but the page is blank. Would appreciate any guidance.

    Thanks
