The ICS8521I-03 is a low skew, 1-to-9 Differential-to-
LVHSTL Fanout Buffer . The ICS8521I-03 has two
selectable clock inputs. Redundant clock pairs, CLK0,
nCLK0 and CLK1, nCLK1 can accept most standard
differential 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 and part-to-part skew
characteristics make the ICS8521I-03 ideal for today’s most
advanced applications, such as IA64 and static RAMs.
