• ADF4360-8 spurs at half output frequency

    I am using the ADF4360-8 to as an input to my IQ receiver which divides the vco frequency by 2. I use a reference frequency of 19.2MHz, an Fpfd of 50kHz and tune the VCO to 300.050MHz (count 6001) and I get these spurs on my ground at 150.000MHz and 150…

  • adf4360-8无法锁定

    求助,adf4360-8芯片无法锁定,输出波形在110M附近跳动,MUXOUT口设置VDD可正常输出VDD,设置锁定检测时为低电平,设置为N DIVIDER OUTPUT或R DIVIDER OUTPUT时为下图。

    电路参考芯片开发板设计,VDD及REFin都正常,程序没有问题可以使开发板产生期望频率,之前以为是滤波电路的问题,后来把直接把开发板的滤波电路接上也是同样问题,重新换了芯片电路板也一样,基本所以地方都排查过了也没找问题出在哪。

  • ADF4360-8 single ended output

    Hi 

      If I do not need the differential outputs on the ADF4360-8, do I only use 50 ohm resistor to terminate the unused output? or i still need to add output matching circuit on unused output.(as Figure 28. Optimum ADF4360-8 Output Stage on datasheet).Thanks…

  • ADF4360-8 PDF value

    Hi Guys, I am working with PLL ADF4360-8. I know we must tuning Reg_R_Counter to PFD value smaller than 8MHz following Datasheet

    If PFD value > 1Mhz, band select is enabled. My project has PDF value equal 6.5MHz after tuning, but still can not work.…

  • ADF4360-8 vtune CP filter

    Hi,

    I am trying to figure out what purpose the filter between vtune and CP has, as that is not really explained in the datasheet.

    Obviously it is a low-pass filter, but what is it filtering?

    What impact does it have on frequency selection?

    I would have…

  • RE: ADF4360-9 performance

    您好,感谢对ADI产品的关注。

    两者的输出频率范围略有不同,ADF4360-9VCO输出端可以进一步分频,所以输出频率范围更宽。另外FOM参数比ADF4360-8也略低。
