Trying to figure out the min. input duty cycle the products will respond to.  I have a very low duty cycle pulse train @ 100MHz that I need to divide down.  Pulse width is on the order of 200fs.

 
Thanks,

 
Tim

    Hi Tim,
    
 
    I don't believe either of these parts will come anywhere close to working. I base this on the maximum input frequency that the divider can accept and the time that would be required to process a 200fS pulse. If we think of the 200fS pulse as being one half of signal train then we end up with a frequency of 2.5THz. I don't think it's going to matter that we only have to divide this signal once every 10nS.
    
 
    Best Regards,
