ICS85310I-11
LOW SKEW, 1-TO-10
DIFFERENTIAL-TO-2.5V/3.3V ECL/LVPECL FANOUT BUFFER
GENERAL DESCRIPTION
The ICS85310I-11 is a low skew, high perfor-
ICS
mance 1-to-10 Differential-to-2.5V/3.3V ECL/
HiPerClockS™ _{LVPECL Fanout Buffer and a member of the}
HiPerClockS™ family of High Perfor mance
Clock Solutions from ICS. The CLKx, nCLKx
pairs can accept most standard differential input levels. The
ICS85310I-11 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 ICS85310I-11 ideal
for those clock distribution applications demanding well de-
fined performance and repeatability.
FEATURES
• 10 differential 2.5V/3.3V LVPECL / ECL outputs
• 2 selectable differential input pairs
• CLKx, nCLKx pairs can accept the following differential
input levels: LVDS, LVPECL, LVHSTL, SSTL, HCSL
• Maximum output frequency: 700MHz
• Translates any single ended input signal to 3.3V
LVPECL levels with resistor bias on nCLK input
• Output skew: 30ps (typical)
• Part-to-part skew: 140ps (typical)
• Propagation delay: 2ns (typical)
• Additive phase jitter, RMS: <0.13ps (typical)
• LVPECL mode operating voltage supply range:
V_CC = 2.375V to 3.8V, V_EE = 0V
• ECL mode operating voltage supply range:
V_CC = 0V, V_EE = -2.375V to -3.8V
• -40°C to 85°C ambient operating temperature
• Lead-Free package fully RoHS complaint
