Figure 41. Mobile DDR SDRAM DQ versus DQS and SDCLK Read Cycle Timing Diagram
NOTE
SDRAM CLK and DQS related parameters are being measured from the
50% point—that is, high is defined as 50% of signal value and low is
defined as 50% of signal value.
The timing parameters are similar to the ones used in SDRAM data
sheets—that is, Table 41 indicates SDRAM requirements. All output signals
are driven by the ESDCTL at the negative edge of SDCLK and the
parameters are measured at maximum memory frequency.
