Sigma调制功能，便可提高其频率精度，大幅降低相位噪音及带内杂散信号，并???持极高的切换速度。系统设计工程师可以利用 Delta Sigma PLL将比较频率提高到很高的水平，以大大降低相位噪音。但高比较频率会导致产生周期滑动(cycle slipping)现象。-Sigma modulation function, can increase its frequency accuracy, dramatically reducing the in-band phase noise and spurious signals, and??? Holders of high switching speed. System design engineers can take advantage of Delta Sigma PLL compares the frequency increased to a very high level in order to significantly reduce the phase noise. However, the high comparison frequency would result in sliding cycle (cycle slipping) phenomenon.
