• HMC853 polarity

    I was looking at HMC853 for reducing the jitter of 25 Gbps transmitter in my FPGA, but looking at the datasheet it seems to operate using negative voltages while the FPGA output is positive (Stratix 10). I have a bitstream which is not dc balanced so…

  • Hmc853 flip flop output rise time

    Dear Help,

        I’m trying to generate pulses with fast tr using the hmc853 flip flop.  The clock inputs are driven through a balance with a differential 100MHz sine wave of 320 mVpp diff., and the D inputs have 50 MHz sine wave with same amplitude.  As…

    This part is EAR99. The attached RFIC selection guide lists the ECCN codes for all of ADI's RF products.


  • RE: 36GHz RF oscillation signal source

    You need a PLL which drives a frequency doubler which drives an amplifier. Possible choices might be ADF4371 (PLL),  HMC1105 (frequency doubler) and HMC7229 (amplifier). These are not the only choices.
