  • Patent number: 5933058
    Abstract: A self-tuning clock recovery phase-locked loop (PLL) includes a programmable divide-by-M, a phase-frequency detector, a programmable voltage-controlled oscillator (VCO), a programmable divide-by-N, and a PLL tuning circuit, which in normal mode operation, perform as a conventional PLL. When the frequency of an input clock signal to the PLL changes by more than a threshold value, however, the PLL tuning circuit causes the PLL to be retuned for the new frequency by adjusting offset and gain parameters in the PLL such that the input voltage to the VCO is mid-way in its input voltage range when the output clock frequency of the PLL is approximately equal to the input clock frequency multiplied by a closed loop gain of the PLL, so that the VCO is operating in a linear region having wide dynamic frequency range.
