2:2 Differential-to-LVPECL/LVDS Clock Multiplexer

The 859S0212I is a 2:2 Differential-to-LVPECL/ LVDS Clock Multiplexer which can operate up to 3GHz. The 859S0212I has 2 selectable differential PCLKx, nPCLKx clock inputs. The PCLKx, nPCLKx 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. The clock select pin has an internal pulldown resistor.
