standard differential input levels.The ICS85211I-03 is char-
acterized to operate from a 3.3V power supply. Guar-
anteed output and par t-to-par t skew character istics
make the ICS85211I-03 ideal for those clock distribution
applications demanding well defined performance and
repeatability. For optimal performance, terminate all outputs.
