DESCRIPTION:
designed to address high-speed clock distribution and multiplication applica-
tions. The zero delay is achieved by aligning the phase between the incoming
clock and the output clock, operable within the range of 10 to 133MHz.
select addresses. By proper selection of input addresses, both banks can be
put in tri-state mode. In test mode, the PLL is turned off, and the input clock
directly drives the outputs for system testing purposes. In the absence of an
input clock, the IDT23S08 enters power down. In this mode, the device will
draw less than 12µA for Commercial Temperature range and less than 25µA
for Industrial temperature range, and the outputs are tri-stated.

... 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 ...
