ICS853111A
LOW SKEW, 1-TO-10
DIFFERENTIAL-TO-2.5V/3.3V LVPECL/ECL FANOUT BUFFER
GENERAL DESCRIPTION
The ICS853111A is a low skew, high perfor-
ICS
mance 1-to-10 Differential-to-2.5V/3.3V LVPECL/
HiPerClockS™ _{ECL Fanout Buffer and a member of the}
HiPerClockS™ family of High Performance
Clock Solutions from ICS. The ICS853111A
is characterized to operate from either a 2.5V, 3.3V or a
5V power supply. Guaranteed output and par t-to-par t
skew characteristics make the ICS853111A ideal for
those clock distribution applications demanding well de-
fined performance and repeatability.
