GENERAL DESCRIPTION
The ICS8535-11 is a low skew, high performance 1-to-4 3.3V Crystal Oscillator/LVCMOS-to-3.3V LVPECL fanout buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS8535-11 has selectable single ended clock or crystal inputs. The single ended clock input accepts LVCMOS or LVTTL input levels and translate them to 3.3V LVPECL levels. The output enable is internally synchronized to eliminate runt pulses on the outputs during asynchronous assertion/deassertion of the clock enable pin.
