58
O
Current set
resistor
RSET
Clock Distribution Current Set Resistor. Connect a 4.12 kΩ resistor from this pin
to GND.
62
O
Current set
resistor
CPRSET
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.
63
I
Reference
input
REFIN (REF2)
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.
64
I
Reference
input
REFIN (REF1)
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.
EPAD
GND
The exposed die pad must be connected to GND.
