Preliminary Information
DS4360 Issue 1.3 September 1999
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 0·5V p-p output. If required, an
external 100 ohm can be connected in parallel to give a
50 ohm output.
