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
