Abstract: A delay time is set only within the variable delay time of a clock driver and cannot be set longer than the variable delay time of the clock driver. A control circuit adjusts the delay amount of a variable delay circuit so as to synchronize a pulse phase after a first pulse outputted from a pulse generation circuit passes through the variable delay circuit N times and a second pulse outputted from the pulse generation circuit.

Abstract translation: 延迟时间仅在时钟驱动器的可变延迟时间内设置，并且不能设置为长于时钟驱动器的可变延迟时间。 控制电路调整可变延迟电路的延迟量，以便在从脉冲发生电路输出的第一脉冲通过可变延迟电路N次之后使脉冲相位同步，并从脉冲发生电路输出的第二脉冲。
