5GHZ 42 Fixed Modulus Divider Preliminary Information
DS4375 Issue 1.4 September 1999
The SP8902 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 a differential current output and provides a direct drive into a 50 ohm load.
