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.
