I want to construct a divide by ten or a divide by 100 frequency 
divider. This is to take my 10 MHz. from my
Rubidium to 1 MHz. or 100 KHz.
I could use the spare 74xx90 chips ( which I have) but I would like to 
make some thing useful for future
uses. What would be a "through the hole" type of IC that would have less

jitter than a 74xx90. I CAN do
surface mount if I have to.

Thanks
