SP8908 (MP)
5GHZ 48 Fixed Modulus Divider
Preliminary Information
DS4359 Issue 1.3 September 1999
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.
