This latched input selects the polarity of the OE pins.  
0 = OE pins active high, 1 = OE pins active low (OE#)  
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.
