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 ICS8521I ideal for today’s
most advanced applications, such as IA64 and static RAMs.
