| Zusammenfassung: | The invention provides one lock phase circuit with wide frequency range and its operation method, which comprises the following steps: in lock phase circuit, using one inner established frequency division parameters determining unit to realize one lock monitor mechanism to monitor its lock phase circuit control voltage; when control voltage is larger or smaller than one set voltage operations, changing system divides to adjust output frequency signals. The invention has wide lock frequency range circuit and its operation method without extra control legs. |
