GENERAL DESCRIPTION

The ICS8521 is a low skew, 1-to-9 3.3V Differ-

ential-to-LVHSTL Fanout Buffer and a member of

the HiPerClockS™ family of High Performance

Clock Solutions from ICS. The ICS8521 has two

selectable 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

pulseson the outputs during asynchronous assertion/

deassertion of the clock enable pin.

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

voltage characteristics make the ICS8521 ideal for today’s

most advanced applications, such as IA64 and static RAMs.
