ICS85211I-01
LOW SKEW, 1-TO-2
DIFFERENTIAL-TO-HSTL FANOUT BUFFER
GENERAL DESCRIPTION
The ICS85211I-01 is a low skew, high perfor-
ICS
mance 1-to-2 Differential-to-HSTL Fanout Buffer
HiPerClockS⢠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 ICS85211I-01 is characterized to
operate from a 3.3V power supply. Guaranteed output and
part-to-part skew characteristics make the ICS85211I-01
ideal for those clock distribution applications demanding
well defined performance and repeatability. For optimal
performance, terminate all outputs.
FEATURES
⢠Two differential HSTL compatible outputs
⢠One differential CLK, nCLK input pair
⢠CLK, nCLK pair can accept the following differential
input levels: LVDS, LVPECL, HSTL, SSTL, HCSL
⢠Maximum output frequency: 700MHz
⢠Translates any single-ended input signal to HSTL
levels with resistor bias on nCLK input
⢠Output skew: 30ps (maximum)
⢠Part-to-part skew: 250ps (maximum)
⢠Propagation delay: 1ns (maximum)
⢠Output crossover Voltage: 0.68V to 0.9V
⢠Output duty cycle: 49% - 51% up to 266.6MHz
â¢
V = 1.4V (maximum)
OH
⢠3.3V operating supply
⢠-40°C to 85°C ambient operating temperature
⢠Available in both standard and lead-free RoHS-compliant
packages
