Figure 40: x4, x8 Data Output Timing – tDQSQ, tQH, and Data Valid Window
NOTE:
1. DQ transitioning after DQS transition define tDQSQ window. DQS transitions at T2 and at T2n are “early DQS,” at T3,
“nominal DQS,” and at T3n, “l(fā)ate DQS.”
2. For a x4, only two DQ apply.
3. tDQSQ is derived at each DQS clock edge and is not cumulative over time and begins with DQS transition and ends with
the last valid DQ transition.
4. tQH is derived from tHP: tQH = tHP - tQHS.
5. tHP is the lesser of tCL or tCH clock transition collectively when a bank is active.
6. The data valid window is derived for each DQS transitions and is defined as tQH minus tDQSQ.
