70 / 155 page  P5021 QorIQ Integrated Processor Data Sheet, Rev. 1 Electrical characteristics Freescale Semiconductor 70 This figure shows the DDR3 and DDR3L SDRAM interface input timing diagram. Figure 9. DDR3 and DDR3L SDRAM interface input timing diagram Tolerated Skew for MDQS—MDQ/MECC tDISKEW ps 2 1600 MT/s data rate –200 200 1333 MT/s data rate –250 250 1200 MT/s data rate –275 275 1066 MT/s data rate –300 300 800 MT/s data rate –425 425 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 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.
