Power Supply / Test mode enable. This pin provides the power supply to the internal PLL. When the
pin is pulled low, the PLL is bypassed and the output clocks directly follow the input clock
PLL supply ground
Reference clock input (Note: -02 version has a pull-down on this pin)
Feedback clock input, connected to FBOUT to complete the loop
Feedback output clock
Ground for all clock outputs
Power supply for all clock outputs
