NOTE:
1. Output phase is indeterminant (0° or 180° from input clock).
ZERO DELAY AND SKEW CONTROL
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.

3.3V ZERO DELAY CLOCK MULTIPLIER
To close the feedback loop of the IDT2308A, the FBK pin can be driven from any of the eight available output pins. The output driving the FBK pin
For applications requiring zero input-output delay, all outputs including the one providing feedback should be equally loaded. Ensure the outputs are
