ICS85310I-31
LOW SKEW, DUAL, 1-TO-5
2.5V/3.3V DIFFERENTIAL-TO-ECL/LVPECL FANOUT BUFFER
GENERAL DESCRIPTION
FEATURES
The ICS85310I-31 is a low skew, high performance • 2 differential 2.5V/3.3V LVPECL / ECL bank outputs
ICS
dual 1-to-5 Differential-to-2.5V/3.3V ECL/LVPECL
HiPerClockS™ _{Fanout Buffer and a member of the HiPerClockS™} ^{• 2 differential clock input pairs}
family of High Performance Clock Solutions from • CLKx, nCLKx pairs can accept the following differential
ICS. The CLKx, nCLKx pairs can accept most input levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL
standard differential input levels. The ICS85310I-31 is charac-
terized to operate from either a 2.5V or a 3.3V power supply. ^{• Maximum output frequency: 700MHz}
Guaranteed output and part-to-part skew characteristics make _{• Translates any single ended input signal to 3.3V}
the ICS85310I-31 ideal for those clock distribution applications _{LVPECL levels with resistor bias on nCLKx input}
demanding well defined performance and repeatability.
• Output skew: 25ps (typical)
• Part-to-part skew: 270ps (typical)
• Propagation delay: 1.7ns (typical)
• Additive phase jitter, RMS: <0.13ps (typical)
• LVPECL mode operating voltage supply range:
V = 2.375V to 3.8V, V = 0V
CC
EE
