General Description
The ICS854S202I is a 12:2 Differential-to-LVDS Clock Multiplexer
which can operate up to 3GHz. The ICS854S202I has twelve selectable differential 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 levels. The fully differential architecture and low propagation delay make it ideal for use in clock distribution circuits.
Features
