Although for slow slew rates the total setup time might be negative (i.e. a valid input signal will not have reached V
at the time of the rising clock transition) a valid input signal is still required to complete the transition and reach V
For slew rates in between the values listed in Table 12, the derating values may obtained by linear interpolation.
These values are typically not subject to production test. They are verified by design and characterization.

Note: - (ac/dc referenced for 1V/ns DQ-slew rate and 2 V/ns DQS slew rate)

- The tIS (base) AC150 specifications are adjusted from the tIS (base) specification by adding an additional 100 ps
lier reference point [(175 mV - 150 mV) / 1 V/ns]
of derating to accommodate for the lower alternate threshold of 150 mV and another 25 ps to account for the ear
