As part of the FE 405 B project a separate output circuit is in the works.  
The universal controller and auxiliary board are the same as used in the 
FE5680A  GPSDO but because of the very low ADEV a separate circuit board that 
divides by  three and has also two ground isolated transformer outputs is in 
the works.The  question is what is the best sine to square wave converter 
with the lowest ADEV  contribution. I am looking at Bruce's circuit using the 
ADCMP600. Any other  ideas?
Thanks   Bert Kehren
