11.3 Single-ended Output Slew Rate
With the reference load for timing measurements, output slew rate for falling and rising edges is defined and measured between V
for single ended signals as shown in below.
[ Table 11 ] Single ended Output slew rate definition
NOTE : Output slew rate is verified by design and characterization, and may not be subject to production test.
[ Table 12 ] Single ended output slew rate
Description : SR : Slew Rate
Q : Query Output (like in DQ, which stands for Data-in, Query-Output)
se : Single-ended Signals
For Ron = RZQ/7 setting
NOTE : 1) In two cased, a maximum slew rate of 6V/ns applies for a single DQ signal within a byte lane.
Single ended output slew rate for rising edge
Single ended output slew rate for falling edge
Single ended output slew rate
- Case_1 is defined for a single DQ signal within a byte lane which is switching into a certain direction (either from high to low of low to high) while all remaining DQ
- Case_2 is defined for a single DQ signals in the same byte lane are switching into the opposite direction (i.e. from low to high or high to low respectively). For the
Parameter
signals in the same byte lane are static (i.e they stay at either high or low).
remaining DQ signal switching into the opposite direction, the regular maximum limit of 5 V/ns applies.
