• HMC746;HMC747:HMC749

    1. I would like to ask the high-speed devices hmc746/747/749, how many volts do they recognize, and how many volts are considered low. In other words, how much differential voltage we should input will be regarded as high and low by these devices.
    2. In…

  • HMC749 cml fpga

    When the CML input and output ports of the hmc series devices are connected to the LVDS or LVPECL interface of the FPGA, how should the capacitance value be determined? For example, HMC749, the D output port of the T flip-flop, it only changes once, and…

  • hmc749 CN port

    My HMC749 development board seems to be burnt out during use and it cannot work normally. When I was plugging in the power, I used an oscilloscope to detect the voltage at the CN terminal, and found that the value was 0V, and the CP terminal was normally…

  • hmc747/hmc746/hmc749 single-ended interface

    How to connect unused input and output ports such as HMC747, HMC749, HMC746, etc. Is it connected in series with 50 ohms to ground? In other words, how to use a single-ended interface instead of a differential interface?

  • Reset time for HMC959 or HMC749

    I am looking for the time it takes the HMC959 (divide by 4) to get out of reset state. Only the  time for it to go into reset is specified in the datasheet. Does anyone know what is the time? I need the same information for the HMC749 (T-flip-flop).

  • Phase Noise Plots for the HMC749 at 10GHz

    Can you please provide Phase Noise Plots for the HMC749 at 10GHz?

  • RE: HMC733 VCO

    Hi Marty,

    thank you for your message.

    Do you think the HMC733 can provide frequencies up to 20.5 GHz ? The datasheet looks giving some margin.

    The additionnal work with flip-flop product (HMC749 for example ?) concerns impedance matching with balanced…

  • Questions about HMC794LP3E

    Hello,

    My customer is considering to use HMC794LP3E and ask some questions about the function of U9 in evaluation schematic(Page 9 , Page 10 of HMC794 Datasheet).

    Please reter below schematic and let me know your opinions about their questions.
