ZARLINK SP8904-MP DATA SHEET

查询SP8904 (MP)供应商

The SP8904 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.
