PRELIMINARY

ICS8521I

Integrated

Circuit

Systems, Inc.

LOW SKEW, 1-TO-9

DIFFERENTIAL-TO-HSTL FANOUT BUFFER

GENERAL DESCRIPTION

FEATURES

The ICS8521I is a low skew, 1-to-9 Differential- • Nine HSTL outputs

ICS

HiPerClockS™

to-HSTL Fanout Buffer and a member of the

• Selectable differential CLK, nCLK or LVPECL clock inputs

• CLK, nCLK pair can accept the following differential

input levels: LVPECL, LVDS, HSTL, SSTL, HCSL

HiPerClockS™family of High Perfor mance 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 assertion/

deassertion of the clock enable pin.

• PCLK, nPCLK supports the following input types:

LVPECL, CML, SSTL

• Maximum output frequency: 500MHz

• Output skew: 25ps (typical)

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.

• Part-to-part skew: 200ps (typical)

• Propagation delay: 1.3ns (typical)

• V_OH= 1.4V (maximum)

• 3.3V core, 1.8V output operating supply voltages

• -40°C to 85°C ambient operating temperature

• Available in both standard and lead-free RoHS

compliant packages
