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.
Alternatively, this pin is a single-ended input for REF2.
Along with REFIN, this is the differential input for the PLL reference.
Alternatively, this pin is a single-ended input for REF1.
Exposed die pad must be connected to GND.
