PLL-tuning system

摘要

A time discrete PLL-tuning system comprises a phase detector and a voltage controlled oscillator (VCO) for tuning the frequency (fVCO) thereof to a frequency equal to N/M times a reference frequency (fREF), with M a factor indicating the number of frequency steps in which a transmitter/receiver channel distance is divided and N the number of frequency steps in which the oscillator frequency is divided. The sampling frequency of the phase detector is substantial equal to the reference frequency (fREF).
