Clock signal generation device, and wireless base station |
摘要 |
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.
