  • HMC494LP3 self oscillation

    Hello everyone!

    I have made a design with HMC494LP3 divider. The design works well if I apply any signal to the positive input (I am using single input only). The problem with design starts when I turn off signal - the board is self osciallating.

    I…

  • RE: HMC547ALC3 state when A & B are at 0V

    Hi One more question on HMC547ALC3.

    I have a DC blocking cap connected to RFC pin. A PLL output is connected to the RFC with AC coupling.

    RF1 and RF2 is connected to HMC494 ( divide by 8)  and HMC438 (divide by 5) frequency divider respectively.

    I have…

  • RE: HMC-493 and HMC-492 self oscillation

    Hi Eric,

    In the past we have found that 8.25k was the appropriate value to prevent self oscillation without RF input for the HMC492, HMC493, and HMC494.

    Best Regards,

  • RE: HMC492 bistable behavior

    Hi,

    It sounds like the divider is self oscillating when the input is removed.  There is an app note on this phenomenon at the link below.  The appropriate value to prevent self oscillation without RF input is 8.25k for the HMC492, HMC493, and HMC494.
