ICS853S024AY REV. A APRIL 30, 2008

General Description

The ICS853S024 is a low skew, 1-to-24

Differential-to-3.3V, 2.5V LVPECL Fanout Buffer and

a member of theHiPerClockS™ family of High

Performance Clock Solutions from IDT. The CLK,

nCLK pair can accept most standard differential

input levels. The ICS853S024 is characterized to operate from

either a 3.3V or a 2.5V power supply. Guaranteed output skew

characteristics make the ICS853S024 ideal for those clock

distribution applications demanding well defined performance and

repeatability.

Features

signaling levels: LVDS, LVPECL, LVHSTL, SSTL, HCSL

levels with resistor bias on nCLK input
