PRELIMINARY

GENERAL DESCRIPTION

The ICS8521I is a low skew, 1-to-9 Differential-

to-HSTL Fanout Buffer and a member of the

HiPerClockS™family of High Performance Clock

Solutions from ICS. The ICS8521I has two se-

lectable clock inputs. The CLK, nCLK pair can

accept most standard differential input levels. The PCLK,

nPCLK pair can accept LVPECL, CML, or SSTL input levels.

The clock enable is internally synchronized to eliminate runt

pulses on the outputs during asynchronous asser tion/

deassertion of the clock enable pin.

Guaranteed output skew, part-to-part skew and crossover

voltage characteristics make the ICS8521I ideal for today’s

most advanced applications, such as IA64 and static RAMs.
