12:2, DIFFERENTIAL-TO-LVDS MULTIPLEXER
PRELIMINARY
ICS854S202I-01
GENERAL DESCRIPTION
The ICS854S202I-01 is a 12:2 Differential-to-
ICS
LVDS Clock Multiplexer which can operate up to
HiPerClockS™ _{700MHz and is a member of the HiPerClockS™}
family of High Performance Clock Solutions from
IDT. The ICS854S202I-01 has 12 selectable dif-
ferential clock inputs, any of which can be independently routed
to either of the two LVDS outputs. The CLKx, nCLKx input
pairs can accept LVPECL, LVDS, CML or SSTL levels. The
fully differential architecture and low propagation delay make
it ideal for use in clock distribution circuits.
