Alex!

Looks mighty fine to me.... The guys Bob, Phil, and others are discussing it
on teamspeak as I type! At least we got Flow! Here! I can follow flow, but
maybe not all the piles of spec sheets in the 'reading room'!

Thanks
Eric

You guys are going way to fast and losing the rest of us. Take a deep
breath, get a cup of coffee and look at this drawing.
Does this, at a high-level, adequately describe what you are advocating? If
all of you agree that it correct, then I will draw out the next level of
detail.

Guido:

Doing all of this fractional stuff digitally and never having to convert 
back to analog is a big win, a huge win.   The facts are the fractional 
N, without having to go back to analog, but retaining an all digital 
character is a huge win since we remove tons of nastiness due to 
attempting to produce analog waveforms.  Our ULTIMATE resolution should 
by a 2^16 word size and in this case that is 2.5 kHz.  It is going to be 
a big win.
