GENERAL DESCRIPTION

The ICS85211I is a low skew, high performance 1-to-2 Differential-to-LVHSTL Fanout Buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The CLK, nCLK pair can accept most standard differential input levels.The ICS85211I is characterized to operate from a 3.3V power supply. Guaranteed output and part-to-part skew characteristics make the ICS85211I ideal for those clock distribution applications demanding well defined performance and repeatability. For optimal performance, terminate all outputs.
