Zusammenfassung:A communications device (100) includes a frequency divider circuit (106) having a plurality of frequency division ratios. The device also includes at least one phase-lock loop (PLL) circuit (101, 102, 103, 104, 110, 112) coupled to at least a signal input of the frequency divider circuit. The PLL circuit includes a local oscillator (LO) circuit (104) including a plurality of voltage controlled oscillators (VCOs) having different frequency tuning ranges. The device further includes at least one control input (105) coupled to at least the frequency divider circuit and the PLL circuit for specifying one of the plurality of VCOs and one of the plurality of frequency division ratios of the frequency divider circuit.
