... REF pin. The PLL feedback is on-chip and is obtained from the CLKOUT pad. In the absence of an input clock, the IDT2309B enters power down, and the outputs are tri-stated. In this mode, the device will draw less than 25μA. The IDT2309B is characterized for both Industrial and Commercial operation ...

... IDT2309B 3.3V ZERO DELAY CLOCK BUFFER ZERO DELAY AND SKEW CONTROL All outputs should be uniformly loaded in order to achieve Zero I/O Delay. Since the CLKOUT pin is the internal feedback for the PLL, its relative loading can affect and adjust the input/output delay. The Output Load Difference diagram illustrates the PLL's relative loading with respect to the other outputs that can adjust the Input-Output (I/O) Delay ...
