SP8908 (MP)
5GHZ ÷ 8 Fixed Modulus Divider
Preliminary Information
The SP8908 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: 360mW (Typ.)
• Surface Mount Plastic Package
