Zero Delay and Skew Control
For applications requiring zero input
output delay, all
outputs must be equally loaded.

OUTPUT LOAD DIFFERENCE: FBK LOAD
CLKA/CLKB LOAD (pF)
To close the feedback loop of the NB2304A, 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
7 pF 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 Figure 3.
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 Figure 3 to calculate loading differences
between the feedback output and remaining outputs. For
zero output
output skew, be sure to load outputs equally.
