Hi Stephane,

You should be able to program the Fo/LD output pin to echo the divider
output. See "Table 4" in the data sheet. If you are intent on getting
/32, you might check out the LMX2430 series. I think (from a very
quick look at the data sheet) that you'll be able to go to lower
division ratios with it. It also has a muxed output that can be
programmed to echo the divider chain output.

Maybe someone else knows a reason this won't work...I haven't actually
done it, but did look into it some time ago and didn't see anything in
the data sheet that would make me think it wouldn't work. Seems like
these chips are a lot easier to get than simple fast prescalers.
Programmable PLL chips from other manufacturers may work well too.
Cheers,
Tom
