Ground pin.
Ground pin.
This pin establishes the reference current for the differential current-mode output
pairs. This pin requires a fixed precision resistor tied to ground in order to
establish the appropriate current. 475 ohms is the standard value.
Ground pin for the PLL core.
3.3V power for the PLL core that also functions as Power Down. Collapsing this
power supply places the device in Power Down mode.
3.3V input for selecting PLL Band Width
0 = High, 1= Low
