ICS853013
LOW SKEW, DUAL, 1-TO-3, DIFFERENTIAL-TO-
2.5V/3.3V/5V LVPECL/ECL FANOUT BUFFER
GENERAL DESCRIPTION
The ICS853013 is a low skew, high perfor-
ICS
mance dual 1-to-3 Differential-to-2.5V/3.3V/5V
HiPerClockS™ _{LVPECL/ECL Fanout Buffer and a member of}
the Hiperclocks^TM family of High Performance
Clock Solutions from ICS. The ICS853013
operates with a positive or negative power supply at 2.5V,
3.3V, or 5V. Guaranteed output and part-to-par t skew
characteristics make the ICS853013 ideal for those clock
distribution applications demanding well defined perfor-
mance and repeatability.
FEATURES
• Two differential LVPECL / ECL bank outputs
• Two differential LVPECL clock input pairs
• PCLKx, nPCLKx pairs can accept the following
differential input levels: LVPECL, LVDS, CML, SSTL
• Output frequency: >2GHz (typical)
• Translates any single ended input signal to
LVPECL levels with resistor bias on nPCLKx input
• Output skew: 40ps (maximum)
• Part-to-part skew: 250ps (maximum)
• Propagation delay: 570ps (maximum)
• Additive phase jitter, RMS: 0.03ps (typical)
• LVPECL mode operating voltage supply range:
V = 2.375V to 5.25V
CC
• ECL mode operating voltage supply range:
V_CC = 0V, V_EE = -5.25V to -2.375V
• -40°C to 85°C ambient operating temperature
• Available in both standard and lead-free RoHS-compliant
