Starting with a 10 second clean up loop for a FEI 5680/GPSDO to now 600 Seconds using Wenzel's j circuit for the Tbolt we have a variety of boards. I am presently out of country but when back will gladly attach some board designs, material cost is minimal  if there is interest.Bert Kehren

What's the bandwidth on the typical cleanup PLL?  How well does that match 
the noise from a Rb?

These are my opinions.  I hate spam.
