Hello,
I am trying to understand how the DLL works to delay the DQS input.
From what I understand, the input clock to the DLL must have the same frequency as the DQS signal and hopefully not much of a phase shift.
Then, using the setting on the DLL, the DQS input signal can be delayed to arrive at a desired time (say DQ center for example).
Is this correct?
If no DLL is available, how might this delay be achieved (using IOE delay chain?)
Thank you!
