Figure 32 on page 60 represents the effective reference load of 25Ω used in defining the
relevant device AC timing parameters (except ODT reference timing) as well as the
output slew rate measurements. It is not intended to be a precise representation of a
particular system environment or a depiction of the actual load presented by a produc-
tion tester. System designers should use IBIS or other simulation tools to correlate the
timing reference load to a system environment.
