Tool/software:
I have used 54AC74 for frequency division (divided by 4) for 64MHz to get 16MHz Square wave output. The below are the results
The input to the flipflop is give from Nand gate IC.I am seeing ringing which is almost 300mV at the top. How do i reduce that ringing. Please let me know whether Is it the behavior of flip flop when we go towards higher frequency(65 to 70MHz) with division by 4?
Also in the datasheet of 54AC74
Min and Max frequency is given differently for switching characteristics and timing requirements. I want to use the flipflop to give clock frequency of 65MHz.Can anyone explain me what does it implies exactly.
