[time-nuts] Generating a stable 26MHz and 19.2MHz from 10MHz

I want go generate a stable 26MHz and 19.2MHz signal with stability in
the 1E-13 range at 1s from my 10MHz BVA.
Have been thinking about dividing the signals down to 1MHz and 100kHz
and PLL (50Hz BW or so) a reasonable stable 26MHz and 19.2MHz OCXO to
that signal. But I'm worried that the division will generate noise so
it will not be stable enough?
Have also been thinking about using a DDS to the 26MHz and 19.2MHz and
then pll, but the DDS subject seems to bee very difficult to get a
grip on. Is it possible to generate a signal with that kind of
stability in the 1s range?
Thanks
Anders
