The SP8910 is one of a range of very high speed low power prescalers for professional applications. 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 risetime. The output stage has internal100 ohm pull up resistors, giving a 05V p-p output. If required, an external 100 ohm can be connected in parallel to give a 50 ohm output.
