Default Drive Strength Table
Series Termination Resistor Values
The singled-ended outputs of the ICS9FGP202A default to either a drive strength
of 2 loads or a drive strength of 1 load. Alternate drive strengths can be
selected via the SMBus. Using the correct resistor value can properly
terminate the output to the transmission line without having to change the
default drive strengths via the SMBus. The default drive strengths for the single
ended outputs are show below, as are the suggested termination resistors for
the above topologies. All values assume Zo = 50 ohms:
