Revision 1.07 – October 4, 2007
Data Sheet
Example 3:
In this example, ECC is enabled. This requires that Stage 3 data be sampled at
(3)
. If ECC is disabled, the system
will still work, but there will be more latency before the data is sampled into RDSP. Again, T
T
= 1.5ns and T
TE
=
4.3ns at worst case conditions.
