| titleOfInvention | Dithering of Digitally Controlled Oscillator Output in Phase Locked Loop |
| abstract | The digitally controlled oscillator (DCO) of the PLL is dithered so that the DCO_OUT signal has a varying frequency at dithered intervals. In one example, the DCO receives an undithered stream of incoming digital tuned words, receives a dithered reference clock signal (REFD), and outputs a DCO_OUT signal so that its frequency change occurs in the dithered interval. When a PLL is used in the local oscillator of a cellular telephone transmitter, the new dithering of the DCO spreads the digital image noise in frequency so that less digital image noise is at a specific frequency offset from the main local oscillator frequency. Spreading digital image noise in frequency allows the noise specification to be satisfied without the need to increase the frequency of the PLL reference clock. By meeting the noise specification by avoiding increasing the frequency of the reference clock, an increase in power consumption is avoided. |
