The ICS85214I is a low skew, high performance 1-to-5
Differential-to-HSTL F a n o u t B u f f e r . The CLK0, nCLK0
pair can accept most standard differential input levels.
The single ended CLK1 input acceptsLVCMOS or LVTTL
input levels.Guaranteed output and part to part skew
characteristics make the ICS85214I ideal for those clock
