    • A wireless base station (11) includes a wireless communication unit (17) and a clock signal generation unit (20). The clock signal generation unit (20) includes a voltage-controlled oscillation unit (21) that outputs a clock signal of an oscillating frequency according to an inputted control voltage, a time information generation unit (22) that generates time information based on the clock signal, a time information comparison unit (23) that compares the time information with reference time information; and a control voltage instruction unit (24) that instructs a control voltage according to the comparison result to the voltage-controlled oscillation unit (21). Accordingly, the oscillating frequency of the clock signal can be kept easily and highly precisely.
    • 无线基站(11)包括无线通信单元(17)和时钟信号生成单元(20)。 时钟信号生成部(20)具备根据输入的控制电压输出振荡频率的时钟信号的压控振荡部(21),基于时钟生成时刻信息的时刻信息生成部(22) 时间信息比较单元,用于将时间信息与参考时间信息进行比较; 以及根据与压控振荡单元(21)的比较结果来指示控制电压的控制电压指令单元(24)。 因此,可以容易且高精度地保持时钟信号的振荡频率。
