ICS8520I-02
LOW SKEW, 1-TO-16
DIFFERENTIAL-TO-LVHSTL FANOUT BUFFER
GENERAL DESCRIPTION
ICS
The ICS8520I-02 is a low skew, high performance
1-to-16 Differential-to-LVHSTL Fanout Buffer and
HiPerClockS™ _{a member of the HiPerClockS™ family of}
High Performance Clock Solutions from ICS. The
ICS8520I-02 has 1 differential 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 ICS8520I-02 ideal for
nterfacing to today’s most advanced microprocessor and
static RAMs.
FEATURES
• Sixteen differential LVHSTL compatible outputs
each with the ability to drive 50Ω to ground
• One differential CLK, nCLK input pair
• CLK, nCLK pair can accept the following differential
input levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL
• Maximum output frequency: 500MHz
• Translates single ended input levels to LVHSTL
levels with resistor bias nCLK input
• V_OH: 1.3V (maximum)
• 40% of V_OH ≤ Vcrossover ≤ 60% of V_OH
• Output skew: 110ps (maximum)
• Part-to-Part skew: 450ps (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
