ABSTRACT:
An analog switch is provided in a phase-locked loop (PLL) synthesizer using direct digital synthesizer (DDS) circuitry, for opening a PLL. The PLL is closed to make operative the DDS circuitry and a fixed frequency divider within an idle time slot of each time-division multiplexing (TDM) frame. For the rest of the frame, the voltage-controlled oscillator within the PLL is held in a "hold state".
