9 Vin Filter input

(Charge pump output) This is the output terminal for the LPF input and charge pump output. When the phase of the programmable divider output (f1/N) is ahead compared to the reference frequency (f REF ), the "source" current state becomes active. If it is behind, the "sink" current becomes active. If the phases are the same, the high impedance state becomes active. 10 Vtu Tuning output This supplies the tuning voltage. 11 V CC3 Power supply voltage 3 Power supply voltage for tuning voltage 28 to 35V
