able 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 out-
puts during asynchronous assertion/deassertion of the clock
enable pin.
Guaranteed output and part-to-part skew characteristics
make the ICS8535-31 ideal for those applications demand-
ing well defined performance and repeatability.
