Abstract
A frequency generator is disclosed. The frequency generator is for generating an oscillator clock according to a reference clock, and the frequency generator is used in a frequency hopping system that switches a carrier frequency among a plurality of channels, and the carrier frequency further carries a modulation frequency for data transmission. The frequency generator includes: a frequency hopping and modulation control unit arranged for generating a current channel according to a channel hopping sequence and a frequency command word (FCW) based on the reference clock, wherein the modulation frequency is higher than a frequency of the reference clock; a reference phase generating unit arranged for generating a reference phase according to the reference clock, the modulation clock, the first FCW, the second FCW, and the third FCW; a digital-controlled oscillator (DCO) arranged for to generating the oscillator clock according to the reference phase. An associated method is also disclosed.
