SP8902/KG/MP1T (tape and reel)
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.
Features
● Very High Operating Speed
● Operation down to DC with Square Wave Input
● Silicon Technology for Low Phase Noise
(Typically better than 2140dBc/Hz at 1KHz)
● 5V Single Supply Operation
● Low Power Dissipation: 335mW (Typ.)
● Surface Mount Plastic Package
