SDR SDRAM CLK parameters are measured from the 50% point—that is,
high is defined as 50% of signal value and low is defined as 50% of signal
value. SD1 + SD2 does not exceed 7.5 ns for 133 MHz.
The timing parameters are similar to the ones used in SDRAM data
sheets—that is,
are driven by the ESDCTL at the negative edge of SDCLK and the
parameters are measured at maximum memory frequency.
