Description
Description The ZL40812 is one of a range of 5V
supply, very high speed low power prescalers for
professional applications with a fixed modulus of divide
by 16. 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 1V p-
p output. See application notes for more details.
