[time-nuts] 63.8976 OCXO is useful

Hi,

I can think of at least one excellent use for the unwanted 63.8976MHz OCXO
that comes free with some of the recently offered FE-5680A units.

It would make a great reference for a DDS synthesizer, such as an
AD9852/AD9854. These chips have a 4x reference multiplier capability, and
thus would provide a clock at ~256MHz.

How useful it would be to have a DDS synthesized signal generator with
sub-milliHz steps, low phase noise, controllable phase and output level,
and 0 - 100MHz output capability!

73,
