What did you do for input protection?
I want to build an input system for the TICC that incorporates some input protection, switchable terminator, possibly settable threshold and edge selects, and a switchable PICDIV divider like the TADD-2 Mini. That would allow inputs of <1 .. 100 (or maybe up to 1000) PPS and 1/5/10/15 MHz inputs.
The main problem I'm having is coming up with an input squarer circuit that is simple and cheap but can handle basically DC-15 MHz. Anybody got any ideas?
