This pin establishes the reference for the differential current-mode
output pairs. It requires a fixed precision resistor to ground.
475ohm is the standard value for 100ohm differential impedance.
Other impedances require different values. See data sheet.
Ground pin for the PLL core.
3.3V power for the PLL core.
