Note:
1. Outputs are non- inverted on ASM5P2308A-2 and ASM5P2308A-3 in bypass mode, S2 = 1 and S1 = 0.
2. Output phase is indeterminant (0° or 180° from input clock). If phase integrity is required, use the ASM5P2308A-2.

Output Load Difference: FBK Load - CLKA/CLKB Load (pF)
To close the feedback loop of the ASM5P2308A, the FBK pin can be driven from any of the eight 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.
