LOW SKEW, 1-TO-2, DIFFERENTIAL-TO-LVPECL/ECL
FANOUT BUFFER
General Description
differential input levels.The ICS85311 is characterized to operate
from either a 2.5V or a 3.3V power supply. Guaranteed output and
part-to-part skew characteristics make the ICS85311 ideal for
those clock distribution applications demanding well defined
performance and repeatability.
