Hi,
I have a problem to solve, and am looking for a few pointers to help.
I need to generate several frequencies and keep them locked together.
The frequencies need to be stable -- which is to say to keep the jitter
of each signal minimally low...on the order of a fraction of a picosecond.
The frequencies I need to generate are the following:
2.5 MHz,
50 MHz,
350 MHz,
400 MHz,
750 MHz, &
800 MHz.
I need sinusoids. I am nervous about the rather tight constraints on
the jitter. Most of the parts I've used are circa 5 psecs of jitter.
Does anyone have any pointers or perhaps a special part that can
handle this constraint?
thanks,
Craig Deibele
