PRELIMINARY

ICS889874

Integrated

Circuit

Systems, Inc.

1:2

DIFFERENTIAL-TO-LVPECL BUFFER/DIVIDER

GENERAL DESCRIPTION

FEATURES

The ICS889874 is a high speed 1:2 Differential- • Two LVPECL outputs

ICS

to-LVPECL Buffer/Divider and is a member of

the HiPerClockS™family of high performance

clock solutions from ICS. The ICS889874 has

a selectable ÷1, ÷2, ÷4, ÷8, ÷16 output divider,

• Frequency divide select options: ÷ 1, ÷ 2, ÷4, ÷8, ÷16

HiPerClockS™

• IN, nIN input can accept the following differential input levels:

LVPECL, LVDS, CML

which allows the device to be used as either a 1:2 fanout

buffer or frequency divider. The clock input has internal

termination resistors, allowing it to interface with several

differential signal types while minimizing the number of

required external components. The device is packaged in

a small, 3mm x 3mm VFQFN package, making it ideal for

use on space-constrained boards.

• Output frequency: > 2.5GHz

• Output skew: 5ps (typical)

• Part-to-part skew: TBD

• Additive jitter, RMS: <0.03ps (design target)

• Supply voltage range:(LVPECL), 2.375V to 3.465V

Supply voltage range: (ECL), -3.465V to -2.375V

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

• Available in both standard and lead-free RoHS compliant

packages
