Description
The ICS8522 is a low skew, 1-to-17 Differential-to-LVHSTL Fanout Buffer and a member of the HiPerClockS? Family of High Performance Clock Solutions from IDT. The ICS8522 has two selectable clock inputs. The CLK, nCLK pair can accept most standard differential input levels. The PCLK, nPCLK pair can accept LVPECL, CML, or SSTL input levels. The clock enable is internally synchronized to eliminate runt pulses on the outputs during asynchronous assertion/deassertion of the clock enable pin.

Guaranteed output skew, part-to-part skew and crossover voltage characteristics make the ICS8522 ideal for interfacing to today's most advanced microprocessor and static RAMs.
