The
Implementing DDR2 PCB Layout on the TMS320DM647/DM648 DMSoC Application Report
(literature number
SPRAAK9
) specifies a complete DDR2 interface solution for the DM647/DM648 as well
as a list of compatible DDR2 devices. TI has performed the simulation and system characterization to be
sure all DDR2 interface timings in this solution are met; therefore, no electrical data/timing information is
supplied here for this interface.
NOTE
TI supports
only
designs that follow the board design guidelines outlined in the application
report, SPRAAA7, cited earlier.
