Note :
1. t
DQSQ
represents the skew between the 8 DQ lines and the respective RDQS pin.
2. t
DQSQ
is derived at each RDQS clock edge and is not cumulative over time and begins with first DQ transition and ends
with the last valid transition of DQs.
3. t
AC
is show in the nominal case
4. t
DQHP
is the lesser of tDQSL or tDQSH strobe transition collectively when a bank is active.
5. The data valid window is derived for each RDQS transitions and is defined by t
DV
.
6. There are 4 RDQS pins for this device with RDQS0 in relation to DQ0-DQ7, RDQS1 in relation DQ8-DQ15, RDQS2 in
relation to DQ16-24 and RDQS3 in relation to DQ25-DQ31.
7. This diagram only represents one of the four byte lanes.
8. t
AC
represents the relationship between DQ, RDQS to the crossing of CK and /CK.
