ICS853111

LOW SKEW, 1-TO-10

DIFFERENTIAL-TO-2.5V/3.3V LVPECL/ECL FANOUT BUFFER

GENERAL DESCRIPTION

The ICS853111 is a low skew, high perfor-

,&6

mance 1-to-10 Differential-to-2.5V/3.3V LVPECL/

HiPerClockS™ ECL Fanout Buffer and a member of the

HiPerClockS™ family of High Performance

Clock Solutions from ICS. The ICS853111

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 ICS853111 ideal for those clock

distribution applications demanding well defined perfor-

mance and repeatability.

FEATURES

• 10 differential 2.5V/3.3V LVPECL / ECL outputs

• 2 selectable differential input pairs

• PCLKx, nPCLKx pairs can accept the following

differential input levels: LVPECL, LVDS, CML, SSTL

• Maximum output frequency: >3GHz

• Translates any single ended input signal to 3.3V

LVPECL levels with resistor bias on nPCLK input

• Output skew: TBD

• Part-to-part skew: TBD

• Propagation delay: TBD

• 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

• Pin compatible with MC100EP111 and MC100LVEP111
