• ADF4116 CE function

    Hello,

    In Pin Function Descriptions in datasheet, it explains about CE pin.

    When  this pin goes low, it says, "puts the charge pump output into three-state mode".

    Could you explain what "three-state mode" is?

    I couldn't find explanations…

  • ADF4116 hold CP voltage

    Hello,

    I'm using ADF416 with 10M REF. I want to hold CP voltage when 10M REF is off.

    Do you know any function to hold CP voltage when  this IC is unlocked?

    Some system on and off 10M REF. So I want hold CP voltage while10M is off.

    Best Regards,

  • ADF4116 Loop Filter Designing

    Need help to design or change the loop filter for adf4116. i.e if I want a loop filter for 200MHz-300MHz frequency band, what value of capacitor and resister and other component should I set or is there any software for designing the loop filter for ADF4116…

    Hello everybody,

    I am using ADF4116+CVCO33CL-0390-0410 to generate 400MHz from 10Mhz as beacon and I'm having some troubles with spurs. I'm increased the current CP to 1mA and increased the PD frequency to 10MHz (max) and  it got better (still…
