ICS853014
LOW SKEW, 1-TO-5
2.5V/3.3V DIFFERENTIAL-TO-LVPECL/ECL FANOUT BUFFER
GENERAL DESCRIPTION
FEATURES
The ICS853014 is a low skew, high performance • 5 differential LVPECL/ECL outputs
ICS
HiPerClockS™
1-to-5, 2.5V/3.3V Differential-to-LVPECL/ECL
Fanout Buffer and a member of the HiPerClockS™
• 2 selectable differential LVPECL clock inputs
family of High Performance Clock Solutions • PCLKx, nPCLKx pairs can accept the following
from ICS. The ICS853014 has two selectable differential input levels: LVPECL, LVDS, CML, SSTL
clock inputs.
• Maximum output frequency: > 2GHz
Guaranteed output and part-to-part skew characteristics
make the ICS853014 ideal for those applications
demanding well defined performance and repeatability.
• Output skew: 13ps (typical)
• Part-to-part skew: 60ps (typical)
• Propagation delay: 460ps (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 = -3.8V to -2.375V
• -40°C to 85°C ambient operating temperature
• Lead-Free package fully RoHS compliant
