GENERAL DESCRIPTION

The ICS853210 is a low skew, high performance dual 1-to-5 Differential-to-2.5V/3.3V LVPECL/ECL Fanout Buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS853210 is characterized to operate from either a 2.5V or a 3.3V power supply. Guaranteed output and part-to-part skew characteristics make the ICS853210 ideal for those clock distribution applications demanding well defined performance and repeatability.
