While is is possible to make this frequency from 10MHz with some phase issues via a cpu driven divider, keep in mind simple-minded hardware guys like me just start with a 3.2768Mhz or 32.768Mhz crystal or oscillator, both of which are very, very common, and not so hard to stabilize. In fact, these specific frequencies are offered with very high stability and precision, for instances where binary division is preferred.

I am not certain what the end use of the resulting frequency is (run a clock or watch maybe?), but keep in mind, many roads lead to the right answer. plus, *if it is a clock,* then 1pps signals are also easily used from the 10Mhz source, avoiding all this hoopla.

Just a reminder, Stuff Day is this coming April 9th, we have guys coming from all over, as far away as Arizona and Alberta. we promise to make the trip worthwhile. I have a ton of PIC 16C711 parts we are giving away if anybody can use them.

all the best,
walter
