描述 Description

The 85311 is a low skew, high perfor- mance 1-to-2 Differential-to-2.5V/3.3V ECL/LVPECL Fanout Buffer. The CLK, nCLK pair can accept most standard differential input levels.The 85311 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 85311 ideal for those clock distribution applications demanding well defined performance and repeatability.
