Description
The ZL40815 is one of a range of 5 V supply, very high
speed, low power prescalers for professional
applications with a fixed modulus of divide by 4. 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 risetimes. The output
stage has internal 50 ohm pull up giving a 1 V p-p
output. See application notes for more details
