I'd be looking at an original clock pulse only as fast as 500Hz and I'd
like to
multiply it by, say, 100.
I've seen clock multipliers, but they state a minimum input frequency of
5MHz. A little too
fast for my application.  Maybe there are others but I haven't been able
to find them.

Could you direct me to some references or how-tos on building my own
clock multiplier?

Thanks,
Erik
