ICS853111-02
LOW SKEW, 1-TO-10
DIFFERENTIAL-TO-2.5V/3.3V LVPECL/ECL FANOUT BUFFER
GENERAL DESCRIPTION
The ICS853111-02 is a low skew, high per-
ICS
formance 1-to-10 Differential-to-2.5V/3.3V
HiPerClockS™ _{LVPECL/ECL Fanout Buffer and a member}
of the HiPerClockS™family of High Perfor-
mance Clock Solutions from ICS. The
ICS853111-02 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 ICS853111-
02 ideal for those clock distribution applications de-
manding well defined perfor mance and repeatability.
FEATURES
