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 HMC987 eval board will not introduce additional skew between outputs when the outputs are terminated in identical loads.  Each output is connected to the sma via a controlled impedance equal length (2728 mils) trace. 

    The HMC987 residual phase noise is very small.  In typical applications only the noise floor differs between input and output phase noise.  Figure 14 plots the noise floor at 100MHz, 2GHz and 4GHz.
