ABSTRACT:
An arrangement for determining a gradient factor for a digitally controlled oscillator has a data alignment device and an identification device. The data alignment device can be supplied a modulation signal, a phase error signal and an oscillator control word. The data alignment device is configured to output a modulation setting word based on the modulation signal, output a time interval magnitude based on the phase error signal and a reference interval, and output an oscillator modulation word based on the oscillator control word. The identification device is configured to adapt and output the gradient factor based on the modulation setting word, the time interval magnitude and the oscillator modulation word.
