hi all, I wrote down some notes on a recent PICDIV build and measurements:
http://www.anderswallin.net/2016/04/picdiv-frequency-divider/
If/when I make v2 of this board:
- any suggestions for boosting the output amplitude of both 1PPS and 10MHz
CMOS? Something that drives 3.3Vpp into 50R with ~few ns rise time?
- any obvious mistakes that cause the phase-noise observed? Mostly I think
50/100Hz and harmonics would be nice to suppress..
thanks!
Anders
