• Reference input design of AD9516

    Hi all,

    My customer has used AD9516-1 reference input in the following conditions.

      - REFIN : Single-ended LVCMOS, AC-Coupled, 10MHz square wave

    Recently, she found out the reference input conditions for 10MHz on the datasheet as below.

    Does she have…

  • Eval-ad9516-1 CMOS interface

    I have an ad9516-1 evaluation board. I want to use two cmos interfaces with different frequencies, but the sixth and seventh interfaces on the evaluation board are not soldered. Therefore, I want to solder the sixth and seventh interfaces, but I don’t…

  • Unused pin of AD9516-3

    Hello, I have some questions about AD9516-3.

    When using an external VCO, how the LF pin should be ?  Should the LF pin be connected to VS, GND or others ?

    And could you tell me other attention when using an external VCO ?

  • ad9516配置问题

    您们好,关于AD9516配置的问题,我使用armLPC1768)配置的ad9516,clk输入,100mhz,没用vco,out8输出,寄存器的设置是评估软件导出的配置信息。另外我用的是双线数据写入读出,sdosdio用示波器测量有信号输入和输出,可是波形一直输不出,用调试软件keil读取sdo的数据也是错误的,也就是说寄存器的值读没读出来,写应该也没写进去,我用的也是cssclksdosdio配置,目前不知道问题出在哪里?用评估软件直接配置没有问题,输出波形正常。我是不是数据手册里面…

  • Abnormal Power Supply to AD9516-1

    Dear,

    My customer is using AD9516-1 for his application.

    By unknown reason, voltage at Ground and 3.3V power are increased to 0.5V and 3.8V respectively.

    In this case, What could be happen to AD9516-1 ?

    Will AD9516-1 not be affected from this power…

  • Matching between AD9516 and CLK buffer

    Hi,

    My customer is using AD9516 with the clock buffer of TI as shown below(refer to attached datasheet).

    She said that if 10MHz input of clock buffer was connected directly to REFIN of AD9516, there was no problem and when she checked clock performance on…

  • AD9516-3电源电流

    AD9516-3的三类电源VS、VS_LVPECL、VCP的电压都有明确注明,CN0243中电源是同一电源,但现在需要每路单独供应,能否给出每路电源的电流消耗?

  • AD9516's power current supply requirements

    HI,

    We noted AD9516 needs three power supply, named VS, VCP and VS_LVPECL, and in the datasheet there are figures 7,8,9,11,12. I am confused about those figures. Is the figure 7, Current vs. Frequency, Direct to Output, LVPECL Outputs, means the current…

  • Suitable frequency reference for AD9516-1

    I am considering using the AD9516-1 evaluation board as a dedicated DAC clock generator for my RF testbench. The target application is evaluation of Wifi (802.11n) modules in the 2.4-6GHz range. The IQ DAC clock rate is 200MHz (we are using AD9779A).…
