GENERAL DESCRIPTION

The ICS85314-01 is a low skew, high performance 1-to-5 Differential-to-3.3V LVPECL fanout buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS85314-01 has two selectable clock inputs. The CLK0, nCLK0 pair can accept most standard differential input levels. The single-ended CLK1 can accept LVCMOS or LVTTL input levels. The clock enable is internally synchronized to eliminate runt clock pulses on the outputs during asynchronous assertion/deassertion of the clock enable pin.

FEATURES
