描述
The 853S202I is a 12:2 Differential-to-LVPECL Clock Multiplexer which can operate up to 3GHz. The 853S202I has twelve select-able differential clock inputs, any of which can be independently rout-ed to either of the two LVDS outputs. The CLKx, nCLKx input pairs can accept LVPECL or LVDS levels. The fully differential architecture and low propagation delay make it ideal for use in clock distribution circuits.
