LOW SKEW, 1-TO-2
DIFFERENTIAL-TO-LVHSTL FANOUT BUFFER
GENERAL DESCRIPTION
The ICS85211I is a low skew, high perfor-
,&6
mance 1-to-2 Differential-to-LVHSTL Fanout
HiPerClockS™ _{Buffer 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 is charac-
terized to operate from a 3.3V power supply. Guaran-
teed output and part-to-part skew characteristics make
the ICS85211I ideal for those clock distribution appli-
cations demanding well defined performance and re-
peatability. For optimal performance, terminate all outputs.
FEATURES
• 2 differential LVHSTL compatible outputs
• 1 differential CLK, nCLK input pair
• CLK, nCLK pair can accept the following differential
input levels: LVDS, LVPECL, LVHSTL, SSTL, HCSL
• Maximum output frequency: 700MHz
• Translates any single-ended input signal to LVHSTL
levels with resistor bias on nCLK input
• Output skew: 30ps (maximum)
• Part-to-part skew: 250ps (maximum)
• Propagation delay: 1ns (maximum)
• Output duty cycle: 49% - 51% up to 266.6MHz
•
V = 1.2V (maximum)
OH
• 3.3V operating supply
• -40°C to 85°C ambient operating temperature
