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:

VCC = 2.375V to 3.8V, VEE = 0V

• ECL mode operating voltage supply range:

VCC = 0V, VEE = -3.8V to -2.375V

• -40°C to 85°C ambient operating temperature

• Lead-Free package fully RoHS compliant
