ABSTRACT:
A clock signal generator can prevent unnecessary power consumption and can lower the power consumption of a system or a chip as a whole. A clock generator has a plurality of multipliers having variable multiplying factors and multiplying a single input reference clock signal by a designated multiplying factor. A plurality of frequency dividers have variable divide factors and divide a clock signal by a designated dividing factor. A clock selector selects a clock signal which has a required frequency according to a status signal STS from each of the functional locks from among the clock signals having a plurality of frequencies generated by the clock generator. The clock selectors stops the operation of the multipliers or the frequency dividers which are generating unused frequencies by switching clock signals.
