† _{Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and}
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values are with respect to network GND terminals.
2. For operation above 25°C free-air temperature, derate linearly at the rate of 5.6 mW/°C.

NOTES:
3. It is recommended that the logic supply terminal (LOGIC VDD) and the VCO supply terminal (VCO VDD) should be at the same voltage
and separate from each other.
4. The bypass capacitor should be located as close as possible to each power supply.
5. The FREFINPUT (pin 3) and PFD OUT (pin 4) terminals are input/output terminals preset for logic function respectively. In normal
operation, the FREFINPUT shoud be tied to GND and PDF OUT should be left unconnected (open).
