Notes:
1. tCISKEW represents the total amount of skew consumed by the controller between MDQS[n] and any corresponding bit that is
captured with MDQS[n]. This should be subtracted from the total timing budget.
2. The amount of skew that can be tolerated from MDQS to a corresponding MDQ or MECC signal is called tDISKEW. This can
be determined by the following equation: tDISKEW = +/–(T/4 – abs(tCISKEW)) where T is the clock period and abs(tCISKEW) is
the absolute value of tCISKEW.
3. Memory controller ODT value of 150
is recommended
