Using CLK as the feedback will always result in synchronized rising edges between ICLK and CLK. However, the
CLK/2 could be a falling edge compared with ICLK. IDT recommends using CLK/2 feedback whenever possible.
This will synchronize the rising edges of all three clocks.
All jitter values are considered typical measured at 25° C with 27Ω termination resistor and 15 pF loads on both CLK
and CLK/2. The feedback is from CLK/2 to FBIN. Note that if an output is unused, it should be left unconnected to
improve output jitter on the active output clocks.
