• ADF4107 issue

    we are using two ADF4107 to produce output frequency, they share one Ref frequency(10MHz), and two same VCO, PFD is 5MHz, step frequency is 10MHz,  Assuming that intial phase of two output frequency 50 degree, why to change R register, two output frequency…

  • ADF4107 programming

    Hi, im designing a PLL comprising of the ADF4107 synthesizer chip, and an external loop filter and VCO. initally i had designed the overall PLL circuit with an MSP430 MCU added in order to load the register values to the synth via SPI. I dont have a good…

  • ADF4107 register sequence

    Hi,

     I am using 4107 PLL for generating stable frequency of 6.9 GHz. ADF4107 configure by three method in that i'm using counter reset method follow the sequence as mentioned in the data sheet but  i'm not getting any update in that can you please…

  • ADF4107 EVB

    What the full P/N for ADF4107 EVB, which not stated in website?

    Can I use EVAL-ADF411XEB1? it means I need to solder the ADF4107 on this EVB?

    kindly share the document for ADF4107 EVB if any.

  • ADF4107 programing

    Hello

    We are programing ADF4107 with USB board (Green) ,But on the 25 pin output of the Board we can't get the CLK signal . we only get the Data signal . Anyone could help ?

  • ADF4107: Phase noise

    Q

    Do you have information on the phase noise of the dividers used in your current
    frequency synthesiser devices ?
    You publish total device phase noise performance, which is usually adequate,
    but I want to use the ADF4107 as a programmable divider…

  • ADF4107 troubles

    Hi there,

    This is not the first PLL I design, neither the first ADF4xxx I'm using but here I'm stuck with a problem I do not achieve to understand and I come here to ask for advices. I may possibly do something incredibly stupid that do not appears as…

  • Replacement ADF4107

    I have a design for control a 1Ghz VCO with an ADF4701.

    The reference input is 10Mhz. But I want to replace it

    for a PLL with better specs. Eg. better S/N performance.

    Anyone a suggestion?

  • ADF4107 problems

    Hi!

    I scoured through the forum posts about this PLL but still couldn't solve my problems with the IC.

    I am using it with a 50MHz quartz oscillator and my own microwave VCO (2.75-3.3GHz).
    I am programming the PLL with an Arduino board and tried to…
