Output Load Difference: FBK Load - CLKA/CLKB Load (pF)

To close the feedback loop of the PI6C2308A, 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.

Maximum Ratings

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.
