NOTES:

3. It is recommended that the logic supply terminal (LOGIC VDD) and the VCO supply terminal (VCO VDD) be at the same voltage and

separated from each other.

4. A bypass capacitor is placed as close as possible to each supply terminal.

5. For stable restart of VCO, VCOIN is 0 V when VCO INHIBIT is pulled down to GND level to disable the VCO INHIBIT function. And

also, VCO IN should be 0 V when the operation will be started by supplying the power.

NOTES:

6. Current into VCO VDD, when VCO INHIBIT = VDD, PFD is inhibited.

7. Current into VCO VDD, when VCOIN = 1/2 VDD, RBIAS = 1 kΩ, VCO INHIBIT = GND, PFD is inhibited.
