PRELIMINARY
Note:
18. t
is the minimum time between a rising CLKA edge and a rising CLKB edge for ORB to transition HIGH and to clock the next word to the FIFO1 output
register in three CLKB cycles. If the time between the rising CLKA edge and rising CLKB edge is less than t
SKEW1
, then the transition of ORB HIGH and
load of the first word to the output register may occur one CLKB cycle later than shown.
