HMC6832 & HMC987

On the HMC6832, 

  1. are there any phase noise plots on the part, the data sheet does not show any information on close in noise at higher frequency’s, my operating range would be from ~500 to 3200MHz
  2. The data sheet in figure 12 shows relative output to output skew on the evaluation board, is there any skew data on the part itself? I am wanting to match up multiple high speed converters to sub picosecond clock delays…

 

On the HMC987,

  1. Re figure 4, is there any skew data for the part itself?
  2. Is there any additional phase noise data on this part? In particular anything near 3.2 and 6.4 GHz?

  • The residual PN of HMC6832 is also very low. A typical measurement result at 2GHz is as follows:
    -151dBc/Hz @ 1kHz
    -158dBc/Hz @ 10kHz
    -161dBc/Hz @ 100kHz

    and noise floor is given for different frequencies and different conditions in Figures 22 to 29.

    Figure-12 shows the de-embedded results so there is not any effect from evaluation board. Additionally all RF traces are matched in the eval board, it does not affect the skew between ports.
