PLL structure for providing local oscillator signals for as transceiver.

摘要

The invention relates to a phase-locked loop structure providing local oscillator signals. In order to enable an improved supply of local oscillator signals, the phase-locked loop structure comprises a first phase-locked loop including a first voltage controlled oscillator and a second phase-locked loop including a second voltage controlled oscillator. A first local oscillator output provides a first local oscillator signal, wherein a signal output by the first voltage controlled oscillator is forwarded to the first local oscillator output. A second local oscillator output provides a second local oscillator signal. A selection component forwards a signal output by the first voltage controlled oscillator or a signal output by the second voltage controlled oscillator to the second local oscillator output. The invention relates equally to a corresponding communication unit and to a corresponding method.
