GENERAL DESCRIPTION

The ICS85310I-21 is a low skew, high performance dual 1-to-5 Differential-to-2.5V/3.3V ECL/LVPECL Fanout Buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The CLKx, nCLKx pairs can accept most standard differential input levels. The ICS85310I-21 is characterized to operate from either a 2.5V or a 3.3V power supply. Guaranteed output and partto-part skew characteristics make the ICS85310I-21 ideal for those clock distribution applications demanding well defined performance and repeatability
