Hi

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. The counter is mentioned on
http://home.online.no/~la8ak/m21.htm , but it is Norwegian text

Search through Goggle groups in sci.electronics.design for a divide
by 3 counter, and follow it with five stages of divide by 2 counters.


96/3 = 32
32/2 = 16
16/2 = 8
8/2 = 4
4/2 = 2
2/2 = 1

You want the odd counter somewhere before the final stage to maintain a
50% duty cycle.
