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.
Guaranteed output and part-to-part skew characteristics make
the ICS8536I-33 ideal for those applications demanding well
defined performance and repeatability.
