[time-nuts] 100 MHz decade Divider II

[Azelio Boriani]

In my opinion, those PLLs should be made unusually fast to have a fast
response from input to output. There is also the EFC low pass response
of the OCXOs.

If one could do a PC board design AND was happy using SOT components that would be the  way to go being smaller and less expensive. By doing it the *obsolete way* I have a way to build that fits my skills level.

IIRC he's been around for over 10 years with a good reputation.  Another factor from buying from his is that he has stock in depth which indicates to me he's a serious source.I'm attaching my rough conceptual schematic toshow what I'm trying to achieve.  Comments appreciated.
