Low Skew, 1-to-2
Differential-to-2.5V/3.3V ECL/LVPECL Fanout Buffer
GENERAL DESCRIPTION
The ICS85311 is a low skew, high perfor-
,&6
mance 1-to-2 Differential-to-2.5V/3.3V ECL/
HiPerClockS™ _{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.The
ICS85311 is characterized to operate from either a 2.5V
or a 3.3V power supply. Guaranteed output and part-
to-part skew characteristics make the ICS85311 ideal
for those clock distribution applications demanding well
defined performance and repeatability.
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:
V_CC = 2.375V to 3.465V, V_EE = 0V
• ECL mode operating voltage supply range:
V = 0V, V = -2.375V to -3.465V
