Abstract
In an example, a phase-locked loop (PLL) circuit includes an oscillator, a frequency search circuit, and an analog control loop. The oscillator is configured to provide a clock signal. The frequency search circuit is configured to measure a first frequency of the clock signal for a first clock control signal, measure a second frequency of a second signal for a second clock control signal, and determine, based on the first frequency, the second frequency, the first clock control signal, and the second clock control signal, a third clock control signal corresponding to a programmed frequency, the third clock control signal for causing the clock signal to have a frequency based on the programmed frequency. The analog control loop is configured to control the oscillator to cause the frequency to converge to the programmed frequency.
