These values are typical values seen by the manufacturing process and are not tested.
The values represented with this voltage parameter would typically be used in a system in which the
expansion bus interfaces a single load of 6pF placed less than 2 inches away from the IXP45X/IXP46X
network processors. This drive strength setting should be used to avoid ringing when minimal loading
is attached. Please use IBIS models and simulation tools to guarantee the design.
The values represented with this voltage parameter would typically be used in a system in which the
expansion bus interfaces four loads of 6pF each. All components are placed no further than 4 inches
away from the IXP45X/IXP46X network processors. This drive strength setting should be used to
avoid ringing when medium loading is attached. Please use IBIS models and simulation tools to
guarantee the design.
The values represented with this voltage parameter would typically be used in a system in which the
expansion bus interfaces eight loads of 6pF and all components are placed less than 6 inches from the
IXP45X/IXP46X network processors. Another use case of this drive strength would typically be four
loads of 6pF operating at 80MHz. This drive strength setting should be used to avoid ringing when
maximum loading or frequency is utilized. Please use IBIS models and simulation tools to guarantee
the design.
