Description
The ZL40810 is one of a range of 5V supply, very high
speed low power prescalers for professional
applications with a fixed modulus of divide by 8. The
dividing elements are static D type flip flops and
therefore allow operation down to DC if the drive signal
is a pulse waveform with fast rise times. The output
stage has internal 50 ohm pull up giving a 1V p-p
output. See application notes for more details.
