How does PLL with frequency translation work?

[Sommes]

I'm not very understand how does the divide by n counter work?
Thank you

** Essentially it counts pulses - when a certain ( pre determined)
count is reached it generates a pulse.

Hello Mr Sommes,

Google is your friend. Here are a few links for you.

Under the heading Higher Frequencies you can see how
the divide by n counter works.

Have a look at pages 4 and 5 and see how the divide by n
counter works.

This link has a bit of interesting history.

See figure 2 for the divide by n counter.
