ABSTRACT:
A phase-locked loop (PLL) integrated circuit includes a voltage-controlled oscillator and a loop filter having first and second input terminals and an output terminal coupled to an input of the voltage-controlled oscillator. A charge pump and a phase-lock accelerator are provided. The charge pump is configured to drive the first input terminal of the loop filter with a pump output signal and the phase-lock accelerator is configured to drive the second input terminal of the loop filter with an analog output signal. The phase-lock accelerator is responsive to a reference clock signal and a feedback clock signal.
