PRELIMINARY

12:2, DIFFERENTIAL-TO-3.3V, 2.5V

LVPECL MULTIPLEXER

ICS853S202I

GENERAL DESCRIPTION

FEATURES

The ICS853S202I is an 12:1 Differential-to-3.3V

• High speed 12:2 differential multiplexer

ICS

HiPerClockS™

or 2.5V LVPECL Clock Multiplexer which can

operate >3GHz and is a member of the HiPerClockS™

family of High Performance Clock Solutions from IDT.

The ICS853S202I has 12 selectable differential clock

• Two differential 3.3V or 2.5V LVPECL output

• Twelve selectable differential clock or data inputs

• CLKx, nCLKx pairs can accept the following differential input

levels: LVPECL, LVDS, CML, SSTL

inputs, any of which can be independently routed to either of the

two LVPECL outputs. The CLKx, nCLKx input pairs can accept

LVPECL, LVDS, CML or SSTL levels. The fully differential archi-

tecture and low propagation delay make it ideal for use in clock

distribution circuits.

• Maximum output frequency: >3GHz

• Translates any single ended input signal to LVPECL levels with

resistor bias on nCLKx input

•

Propagation delay: 690ps (typical)

Input skew: TBD

Output skew: 25ps (typical)

Part-to-part skew: TBD
