Hi,
I am using the TMS320DM6467T data sheet SPRS605B July 2009 Revised July 2010 and the Davincihd1080p_EVM_Layout_revb as a reference board.
Looking at page 219 of the data sheet, it said that DQGATEL length should be calculated as follows:
DQGATEL length = CK length + (DQS0 total length + DQS1 total length)/2.
So according to the data sheet DQLGATEL total length should be: 1556 + (940 + 831)/2 = 2441 mills
But on the reference board I find the following: 1205 + 523 = 1728 mills
Can you please explain why the calculations are different in the reference design documentation vs the datasheet?
Regards,
TG
