IDT23S08
3.3V ZERO DELAY CLOCK MULTIPLIER
COMMERCIAL AND INDUSTRIAL TEMPERATURE RANGES
ZERO DELAY AND SKEW CONTROL
To close the feedback loop of the IDT23S08, 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.
For applications requiring zero input-output delay, all outputs including the one providing feedback should be equally loaded. Ensure the outputs are
loaded equally, for zero output-output skew.
