ICS853S012I

12:1, Differential-to-3.3V, 2.5V LVPECL Clock/Data Multiplexer ICS853S012I DATA SHEET General Description The ICS853S012I is an 12:1 Differential-to-3.3V or 2.5V LVPECL Clock/Data Multiplexer which can operate up to 3.2GHz. The ICS853S012I has twelve differential selectable clock inputs. The CLK, nCLK input pairs can accept LVPECL, LVDS or CML levels. The fully differential architecture and low propagation delay make it ideal for use in clock distribution circuits. The select pins have internal pulldown resistors. Features High speed 12:1 differential multiplexer One 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 Maximum output frequency: 3.2GHz Translates any single ended input signal to LVPECL levels with resistor bias on nCLKx input Additive phase jitter, RMS: 0.144ps (typical) Part-to-part skew: 250ps (maximum) ...
