HMC705 / HMC794 frequency divider

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,

  • Hi Tim,

    I'd like to get little more information & confirmation before I give you an answer. 

    1) Can you confirm 200 fS pulse width? That's extremely narrow. Could it be 200pS? I would be curious to know how a pulse width this narrow was measured.

    2) What is the drive level / amplitude of the 200fS pulse?

    3) What division ratio does the customer need?

    Thanks,

    Marty
