1. a phase place is engulfed device, receives a plurality of leggies with reference to clock pulse, and produces an output clock pulse, and leggy is identical with reference to the frequency of clock pulse, phase place is different, it is characterized in that this phase place engulfs device and comprise:

  • One multiplexer receives leggy with reference to clock pulse, and selects leggy to export with reference to clock pulse with reference to one in the clock pulse according to a Selecting phasing signal, as described output clock pulse;

    AndOne phase place is engulfed control unit, according to a phase place amount of engulfing and a reference signal, and by non-bit mode sequentially, relatively after this phase place amount of engulfing and this reference signal, produces phase control signal;

    AndTiming selection unit is exported this Selecting phasing signal according to this phase control signal.
