The 74HC4040 is a 12-stage binary ripple counter with a clock input (CP),
It has an overriding asynchronous master reset input (MR) and twelve parallel outputs.
Each counter stage is a static toggle flip-flop.
...and the answer to the question is ......yes
Yes to that I was way off base? lol
NO NO - sorry....NO
You were right - it's clock distribution
Haha, ok mate
So just putting in a nice TCXO should do fine then.
That's it...Jims
The man there - Stanton is his name is a fantastic guy.
Only praise for him and his site.

Well, in my mind it's an upgrade on 1PPM so I'll pay for one.
Guaranteed... it won't be worse !! haha
I agree.
I'm sure we can tweak the hell out of this clock and as soon as I'm nearly ready to put it into the new machine I'll have a go at it.
Tants, bigger FC's and snubbers on the diodes for a start.
I have a small isolating / screening can with a lid which I'll be placing over the TCXO too once I swap it.
I may even give it more VA and run it at 8 volts instead of 12
We can more out of it.

I ment to put on the DAC pcb, wasn't sure you were talking about that or the Valab clock board?
I guess my mind wandered a bit.
I'm on your dac thread - not the CD one
Yes I meant the valab clock - it can be improved but this is not relevant here sorry !!!
No problems mate
I'll keep the above mentioned in mind for the valab clock, and I'll get the .5ppm TCXO for my Dac-build. Thinking of doing as you said, but maybe use copper to shield the TCXO.
