• RE: VR connection for HMC745

    I liked to know why VR is connected to GND in HMC745 evaluation board.

    If VR is connected to GND, we don't have any output. right?

    In HMC744, HMC746,HMC748 evaluation board, Shorting VR is to VCC.

  • RE: Request mesuring data about jitter values of HMC744LC3 & HMC850LC3

    The worst case total jitter value for HMC744 and HMC850 is Tj = Dj + 2nRj = 6 + 0.2*7  = 7.4ps and cascaded is 10.4ps max for 1e-12 BER. Typically this value would be Tj=3.4ps for a single part and 4.8ps for cascaded.

  • 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.
