 技術摘要： |
一種時脈產生裝置,包括頻率合成器、調變時脈訊號產生模組、延遲調整模組以及頻率調整單元。其中調變時脈訊號產生模組與頻率調整單元同步展頻訊號與數位碼訊號的調變頻率,延遲調整模組調整展頻訊號與數位碼訊號間延遲誤差,以使數位碼訊號具有與展頻訊號相同的調變頻率,且與展頻訊號互為反函數。頻率調整單元將數位碼訊號輸出至頻率合成器中的三角積分調變器,以使頻率合成器輸出為一單頻時脈訊號。
A clock generation device having a frequency synthesizer, a modulation clock signal generation module, a delay adjustment module and a frequency adjustment unit. The modulation clock signal generation module and the frequency adjustment unit synchronize the modulation frequencies of a spread-spectrum signal and a digital code signal, the delay adjustment module adjusts a delay error between the spread-spectrum signal and the digital code signal, so as to make the digital code signal have the same modulation frequency as the spread-spectrum signal has, wherein the digital code signal and the spread-spectrum signal are inverse function of each other. The frequency adjustment unit outputs the digital code signal to a delta-sigma modulator of the frequency synthesizer, so as to let the frequency synthesizer outputs a single frequency clock signal
