GENERAL DESCRIPTION

The ICS85311 is a low skew, high performance 1-to-2 Differential-to-2.5V/3.3V ECL/LVPECL Fanout Buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The CLK, nCLK pair can accept most standard differential input levels.

FEATURES

• 2 differential 2.5V/3.3V LVPECL / ECL outputs

• 1 CLK, nCLK input pair

• CLK, nCLK pair can accept the following differential input

levels: LVDS, LVPECL, LVHSTL, SSTL, HCSL

• Maximum output frequency up to 1GHz

• Translates any single ended input signal to 3.3V LVPECL

levels with resistor bias on nCLK input

• Output skew: 15ps (maximum)

• Part-to-part skew: 100ps (maximum)

• Propagation delay: 1.4ns (maximum)

• LVPECL mode operating voltage supply range:

VCC = 2.375V to 3.465V, VEE = 0V

• ECL mode operating voltage supply range:

VCC = 0V, VEE = -2.375V to -3.465V

• 0°C to 70°C ambient operating temperature

• Industrial temperature information available upon request
