Reference Load for AC Timing and Output Slew Rate
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 pre-
sented by a production tester. Sys-tem designers should use IBIS or other simulation tools to correlate the timing refer-
ence load to a system environment. Manufacturers correlate to their production test conditions, generally one or more
coaxial transmission lines terminated at the tester electronics.
