Propagation Delays (ns)
Loads per Half Column [a]
a. The array distributed networks consist of 40 half columns and the global distributed networks consist
of 44 half columns, each driven by an independent buffer. The number of half columns used does not
affect clock buffer delay. The array clock has up to 8 loads per half column. The global clock has up
to 11 loads per half column.
