for my quite unstable counters I've got some 0.1ppm 9.6MHz VCXO's
(guaranteed over temperature range -20...+20°C), the problem is that
the original XO is 1MHz with 7490 divider, and now I need a divide by
96 downcounter. The VCXO drives a 74LS14, so it shouldn't be any fan
out problem, but I am not aware what is the readily available divider
to choose.
I really should have remembered the 74HC40103 presetable divider - I
designed one into a circuit just a few years ago..... There is a fairly
similar 40102.
My suggestion of the 74HC4059 was overkill by a hard-to-get part.
