描述
The 8521 is a low skew, 1-to-9 Differential-to-HSTL Fanout Buffer. The 8521 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 8521 ideal for today's most advanced applications, such as IA64 and static RAMs.
