Notes:
[5] Stated timing for worst case Propagation Delay over process variation at VCC=3.3V and TA=25
°
C.
Multiply by the appropriate Delay Factor, K, for speed grade, voltage and temperature settings as spec-
ified in the Operating Range.
[7] The array distributed networks consist of 88 half columns and the global distributed networks consist of
92 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 18 loads per half column. The global clock has up
to 20 loads per half column.
