Output Load Difference: FBK Load - CLKA/CLKB Load (pF)
To close the feedback loop of the PI6C2308, the FBK pin can be
driven from any of the 8 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 graph above.
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.
