Zero Delay and Skew Control
For applications requiring zero input-output delay, all
outputs must be equally loaded. To close the feedback loop
of ASM5P23S04A, the FBK pin can be driven from any of
the four available output pins. The output driving the FBK
pin will be driving a total load of 7pF plus any additional
load that it drives. The relative loading of this output (with
respect to the remaining outputs) can adjust the input
output delay. This is shown in the above graph. For
applications requiring zero input-output delay, all outputs
including the one providing feedback should be equally
loaded. If input-output delay adjustments are required, use
the above graph to calculate loading differences between
the feedback output and remaining outputs. For zero
output-output skew, be sure to load outputs equally.
