Dear Jim,
Thank you for your feedback.
The very short version: this design works 'on paper', but there are a few
undocumented unknowns that I can only resolve by actually building and
testing it.

Hello,
This is a topic that interest me greatly as well. Some of the work we have
done uses a digital frequency tracking loop to generate frequency errors
directly from sampled data using a sampling system and ethernet system of our
own design. We opted for using a look-up table-based DDS in

Excellent and exciting work! Thanks for sharing with the newsgroup...
I have a couple of questions:
1. The input bandwidth of the digitizer chip is 750 MHz (very impressive), but
what happens to input noise that is aliased? When sampling at 10MHz (plus
offset) everything above
