I need to make a phase stable divide by 100 frequency divider. The
input signal is 10Mhz, and I need 100kHz output. Phase shift isn't
important, as long as it is stable. Should a 74HC390 do the job?
If so, the 10MHz input is around 2-3VRMS, and I need to get a TTL
level square wave to input to the ripple counter, correct? Any
suggestions about how to do that?
Is there another EASY way to go about doing this (i.e., no assembly
language, I'm pretty poor at writing code).
If it helps, I'm trying to check the accuracy of the variable phase
portion of a 3325b. In the manual it calls for another signal
generator at 100kHz, and measure time interval between the uut and
other std. The problem I'm having is none of our signal geneartors go
down that low, besides the 3325b. I'd like to just divide the 10MHz
reference and use it as the other signal, but frequency must be exact,
and there can't be any phase drift. There should be no frequency
error (negligable would be more proper) with a divider, should there?
All suggestions appreciated.
Thanks,
Steve
