Clock Distribution Current Set Resistor. Connect a 4.12 kΩ resistor from this pin
to GND.
Charge Pump Current Set Resistor. Connect a 5.1 kΩ resistor from this pin to GND.
This resistor can be omitted if the PLL is not used.
Along with REFIN, this is the differential input for the PLL reference. Alternatively,
this pin is a single-ended input for REF2. This pin can be left unconnected when
the PLL is not used.
Along with REFIN, this is the differential input for the PLL reference. Alternatively,
this pin is a single-ended input for REF1.This pin can be left unconnected when
the PLL is not used.
The exposed die pad must be connected to GND.
