    I use 25 MHz as the input XREFP of the HMC. I would like to receive your sample code to evaluate my code as it does not work.

  • HMC833 Register settings

    Hello - we are using the HMC833 as a LO for our receiver and some questions came up on register settings.

    1 - Several of the registers have descriptions to program specific bits to values other than their defaults.  If the default register values are acceptable…

  • HMC833 serial

    Hello, comrades!
    I'm writing app that rules board with HMC833 and some points in datasheet is not fully clear for me.
    Page 41 says that "Host places the 24 data bits on the next 24 falling edges of SCK, MSB first". Did it means that i should place 24…

  • HMC833 output power

    Hello,

    In both the Electrical Specifications and Figure 9 graphs in the HMC833's datasheet, the output power values ​​at 6 GHz are about -11, -7, and -5 dBm.

    Does Electrical Specification include product variation as well as temperature variation?

  • HMC833 unlocks at low temperature

    Hi all,

    I'm using the HMC833 for synthesis of a carrier in the band 2200-2300MHz. Everything went fine up to now but when testing the equipment at -20ºC I observe that the lock of the VCO is unstable and it gets unlocked many times within one second …

  • HMC833 Integer Mode Issue

    Hello

    I am using HMC833 IC in my design.

    Up to now I have used it in fractional mode and everything was fine.

    Due to some spurious signals I would like to change its mode to integer one.

    I have changed the code accordingly but for some reason I receive…

  • HMC833 can't lock after supply power off / power on at high temperature

    Hello,

    We are experiencing the following issue with our HMC833 :

    1. The PLL lock fine at 25°C at 2880MHz
    2. then we ramp up the temperature at 60°C
    3. The pll is still locked and workng fine
    4. We power off then power on the board with the HMC833
    5. We apply…
