5.4 Differential Output Slew Rate
5.4.1 Differential Output Slew Rate Definition
Differential output slew rate for rising
Differential output slew rate for falling
Note: Output slew rate is verified by design and characterization, and not 100% tested in production
5.4.2 Differential Output Slew Rate
Description: SR: Slew Rate, Q: Query Output (like in DQ, which stands for Data-in, Query-Output), diff: Differential Signals, For Ron = RZQ/7 setting
5.5 Reference Load for AC Timing and Output Slew Rate
The following figure represents the effective reference load of 25 ohms used in defining the relevant AC timing parameters
of the device as well as output slew rate measurements. It is not intended as a precise representation of any particular
system environment or a depiction of the actual load presented by a production tester. System designers should use IBIS
or other simulation tools to correlate the timing reference load to a system environment. Manufacturers correlate to their
production test conditions, generally one or more coaxial transmission lines terminated at the tester electronics.
