Dear nuts,
Triggered by Ulrich's very interesting thread on nasty DDS features, I would
like to submit for comments an idea for an application of DDS technology
which hopefully does not suffer from them. We have a need at CERN to
distribute RF signals

A similar scheme is used in almost all modern PC clock distribution
chips. A bunch of PLLs on
