The
Differential-to-3.3V LVPECL Clock Generator. The CLK, nCLK
pair can accept most standard differential input levels.The
ICS87354I is characterized to operate from a 3.3V power
supply. Guaranteed output and part-to-part skew
characteristics make the ICS87354I ideal for those clock
distribution applications demanding well defined
performance and repeatability.
