1. multi-phase clock to ur integer divider
2. using PLL , fout=fref*M/N
 

Re: non-integer divider

Multiply by 2 and divide by 5 (fo = fi x 2/5 = fi / 2.5 )

What are you trying to divide - voltage, frequency, binary number, ... ?
 

non-integer divider

Dear All,
Thanks all response.
My target is the frequency divider using normal
logical circuit . In actually, I had got the divider circuit
with divisor 2.5. But I am interesting about how to
analysis or design the non-integer divider by myself.
