ICST ICS85311
The ICS85311 is a low skew, high performance 1-to-2 Differential-to-2.5V/3.3V ECL/ HiPerClockS™ LVPECL 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.T h e ICS85311 is characterized to operate from either a 2.5V or a 3.3V power supply. Guaranteed output and partto-part skew characteristics make the ICS85311 ideal for those clock distribution applications demanding well defined performance and repeatability.FEATURES
● 2 differential 2.5V/3.3V LVPECL / ECL outputs● 1 CLK, nCLK input pair
● CLK, nCLK pair can accept the following differential input levels: LVDS, LVPECL, LVHSTL, SSTL, HCSL
● Maximum output frequency up to 1GHz
● Translates any single ended input signal to 3.3V LVPECL levels with resistor bias on nCLK input
