GENERAL DESCRIPTION

The ICS8523I-03 is a low skew, high performance 1-to-4 Differential-to-LVHSTL fanout buffer and a member of the HiPerClockS? family of High Performance Clock Solutions from ICS. The ICS8523I-03 has two selectable clock inputs. The input pairs can accept most standard differential input levels. The clock 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 ICS8523I-03 ideal for those applications demanding well defined performance and repeatability.
