WebNov 2, 2014 · It does this by using sophisticated methods including on-die termination (ODT), read/write leveling (using a “fly-by” topology to deliberately introduce flight-time skew, thereby avoiding simultaneous switching noise), Vref tuning, CMD/CTL/ADDR timing training, and other methods. WebDDR timing variations are mainly associated with board design and selected DDR device type. To a lesser extent, DDR timing are influenced by parametric deviations between manufactured i.MX53 ICs, DDR devices, and boards. Changing ambient temperature and product age can also have a minor effect on DDR timing.
