• ADF4116

    Hello, i'm tryng to use a microcontroller to set an adf4116;

    i have calculate my register value using INT-N PLL software, i load by a my sPI routine the N,R,FL register but not have any result...

    Mi Spi is configure to have qa clock og 5 MHz …

  • 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…

    Does ADF4116 can replace LMX2306 completely, including the software parameter configuration (the same control word)?

  • ADF4116 and "Delay" and "Sync" bits


    for ADF4116 registers calculation I am using an "Analog Devices Int-N PLL Software" v7.4.3 application. 

    On "Main Control" window there is mention of two bits "Delay" and "Sync".

    Changes of these bits…

    It is not finish today.

    I use my old Arduino test software (for ADF4110) to send the values in the latches

    for the moment, Pll is not locked.

    I have a question :

    Latches are 21 bits long, I have three solutions:

    Beware : when I copy/paste S-parameters values from datasheet pdf file, negative sign is wrong #ascii code (0x96 vs 0x2D).

  • RE: ADF4110 Channel Spacing

    Try this:

    • Set R counter to 12.
    • Set Reference Latch [19:16] = 0b0111.

    This might output a 50:50 1 MHz signal on muxout. If not, then, unfortunately, the 4% duty cycle is the only option with the ADF4001.

    The ADF4110 or ADF4116 definitely supports…
