GENERAL DESCRIPTION

The ICS853031 is a low skew, high performance 1-to-9 Differential-to-2.5V/3.3V LVPECL/ECL Fanout Buffer and a member of the HiPerClockS? family of High Performance Clock Solutions from ICS. The ICS853031 has two selectable clock inputs. The CLK, nCLK pair can accept most standard differential input levels. The PCLK, nPCLK pair can accept LVPECL, LVDS, CML, or SSTL input levels. The clock enable is internally synchronized to eliminate runt pulses on the outputs during asynchronous assertion/deassertion of the clock enable pin.
