ICS87354I

PRELIMINARY

The ICS87354I is a high performance ÷4/÷5 Dif-

ferential-to-2.5V/3.3V ECL/LVPECL Clock Genera-

tor and a member of the HiPerClockS™ family of

High Performance Clock Solutions from ICS. The

CLK, nCLK pair can accept most standard differ-

ential input levels. The ICS87354I 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 ICS87354I ideal

for those clock distribution applications demanding well defined

performance and repeatability.

• 1 differential 2.5V/3.3V LVPECL / ECL output

• 1 CLK, nCLK input pair

• CLK, nCLK pair can accept the following differential

input levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL

• Maximum output frequency: 250MHz

• Input frequency: >1GHz

• Translates any single ended input signal to

3.3V LVPECL levels with resistor bias on nCLK input

• Output skew: 38ps (maximum)

• Part-to-part skew: 375ps (maximum)

• Propagation delay: 2.1ns (maximum)

• LVPECL mode operating voltage supply range:

V

• ECL mode operating voltage supply range:

V

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