ICS85310I-01
LOW SKEW, 1-TO-10
DIFFERENTIAL-TO-2.5V/3.3V ECL/LVPECL FANOUT BUFFER
GENERAL DESCRIPTION
The ICS85310I-01 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-01 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-01 ideal
for those clock distribution applications demanding well
defined performance and repeatability.
FEATURES
⢠Ten differential 2.5V/3.3V LVPECL / ECL outputs
⢠Two selectable differential input pairs
⢠CLKx, nCLKx pairs can accept the following differential
input levels: LVPECL, LVDS, 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 = 2.375V to 3.8V, V = 0V
CC
EE
⢠ECL mode operating voltage supply range:
VCC = 0V, VEE = -2.375V to -3.8V
⢠-40°C to 85°C ambient operating temperature
⢠Available in both standard and lead-free RoHS compliant
packages
