ICS8520

LOW SKEW, 1-TO-16

DIFFERENTIAL-TO-3.3V LVHSTL FANOUT BUFFER

GENERAL DESCRIPTION

The ICS8520 is a low skew, high performance

1-to-16 Differential-to-3.3V LVHSTL Fanout Buffer

and a member of the HiPerClockS™ family of

High Performance Clock Solutions from ICS. The

ICS8520 has 1 clock input pair. The CLK, nCLK

pair can accept most standard differential input levels.

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

voltage characteristics make the ICS8520 ideal for interfac-

ing to today’s most advanced microprocessor and static

RAMs.

FEATURES

• 16 differential 3.3V LVHSTL outputs each with the ability to

drive 50

Ω to ground

• 1 differential CLK, nCLK input pair

• CLK, nCLK pair can accept the following differential input

levels: LVDS, LVPECL, LVHSTL, SSTL, HCSL

• Maximum output frequency up to 500MHz

• Translates single ended input levels to LVHSTL levels with

resistor bias nCLK input

• Output skew: 50ps (maximum)

• Part-to-part skew: 250ps (maximum)

• Propagation delay: 1.6ns (maximum)

• VOH: 1.2V (maximum)

• 40% of VOH

≤ Vcrossover ≤ 60% of VOH

• 3.3V core, 1.8V output operating supply voltages

• 0°C to 70°C ambient operating temperature
